An H-Bridge (Full-Bridge) driver is quite popular in driving loads such as brushed DC motors and it is widely used in robotics and industry. The main advantages of using an H-Bridge driver are high efficiency, rotation direction change, and breaking the motor. In this article/video, I have introduced a complete H-Bridge DC motor driver using four IR3205 power MOSFETs and two IR2104 MOSFET drivers. Theoretically, the above-mentioned MOSFET can handle currents up to 80A, however, in practice we can expect to get currents up to 40A if the MOSFET temperature is kept as low as possible, using a big heatsink or even a fan.

H-Bridge DC Motor Driver [40A, Power Mosfets]
Спасибо Большое
Nicely done. I modified my pump controller to use a half-bridge driver as you suggested and it's been working flawlessly for months. Thanks for the help.
You're welcome Christie
Hello, I am from Argentina, excuse my English! Very good project. I am working on a replacement for the famous IBT-2 BTS-7960, I do it with IR2110 and channel n mosfet, also a dead time logic so as not to destroy the mosfets. This video inspires me to do it!
No problem, if you practice English, then you are a BIG step ahead of others! It really depends on the current consumption of the load and the choice of the MOSFETs that could tolerate your rush currents
Very nice explanation; I found out the hard way about needing Schottkys across the FET drain to source, they are definitely needed for driving the bigger motors. I kept blowing the FETs and it took a lot of looking around to find the cause and explanation.
Thanks. Generally, it is much better to use those external diodes. I explained why in the article.
great video and project. I combined with ESP32 to control the motors (I am using two H-bridge drivers) over bluetooth using my smartphone.
You're welcome
Can you explain how you made the button connections of the engine? How will the connections of the 4-legged buttons be ?
I think you use Google translate. for buttons, as you see in the video, I used a demo board and connected each button to an Arduino PIN (Digital Input PIN). the buttons are named "tactile push buttons". Reading button status is a basic Arduino project. I used an Arduino library for easier reading as well (JC_Button)
I build the circuit and run it. I only had a problem when I pressed the reverse engine buton. I think I made a mistake in the software part you shared.
Thank you.
Keep trying and practice. Invest some time. the code is easy
Hello sir. I have question about IR2104 Vcc and Motor Vcc. I have 12V battery and 12V 380W DC motors for our robot. If IR2104 Vcc and Motor Vcc supply same terminal with my 12V battery, will I face any problem ? I don't want extra pinout for IC Vcc our design, because my battery and motor are 12V. In this video you supply Vccs same power terminal.
You can do that, both supplies share a common ground. minimum voltage is 12V. but the voltage of the driver side should NOT go higher than 12V, but the motor side can go higher
Thanks for your good work on this driver. I wonder why you do not measure the current in the motor. I am interested to see how it performs at 15 Amps for a sustained time.
Thanks, I received similar requests from two other visitors as well. No problem, I will add the current feedback, however, that's not a difficult task. The encoder is even better to keep the torque identical all the time.
Nice work. This would almost be perfect with my project. Would have to add current sensing ( ACS758LCB-CB-100B) to the PCB.
Curious if the circuit could switch to motor regeneration when coasting.
Thanks Neil. Yes, you can monitor the motor using an encoder or a shunt resistor or a sensing chip as the one you mentioned, however, this board is a driver, you can add these on a separate controlling board with an MCU.
Me suscribi a su canal para ver y aprender mas con estos proyectos tan interesantes!! Saludos!!
Thanks
This is a cool idea. I was going to swap out the FETS for 100V-40A ones to drive with a 80V lawnmower battery. I ordered the boards from PCBway, but as I started looking for the individual components, I can't find anyone who stocks the IR2104 driver! Any ideas on where to find?
That's a pretty normal component. search the component on componentsearchengine.com and check the stock and prices
The project was pretty self explanatory. But how many V should we get the VCC value in the circuit schematic?
I don't have the schematic in front, but the voltage of the driver (not the motor) must be 12V fixed.
Hello and thanks for the video!Can I only switch the Mosfets for having a power supply of 120V?
you should change some capacitors and the MOSFETs because your input voltage is higher than the voltage of these components
@@MyVanitar Thanks for the reply.The capacitors I have to change are C5,C6,C7 am I right?
@@upbgenoob5488 honestly the PCB should be modified to follow the higher voltage standards, but what I told you was the minimum action, otherwise those components will explode
Thank you Sir your channel is Amazing
Most welcome
Is there a way to modify this board work without digital inputs and just use a pot to vary the motor speed and or PWM signal
use a PWM generator at the input. No change should be done for this circuit because it is a Driver, the PWM generator can be on the same board with driver or at another board and connected to the driver by wires
thank you for explaining
you are the best
Glad it helped!
Hi excelente video but I was wondering, did you prove your H bridge with another Voltage supply than 12V?.
I made one of this h bridges but mine doesn't work when have a superior Vs supply and I don't know why
The voltage of the driver side should be always 12V (fixed and regulated). The load side can be changed. in my circuit, I have also used some capacitors. be careful about the rated voltages of the load capacitors and increase them if your voltage is higher
@@MyVanitar max output voltage can go upto ??
Should’nt Q1 and Q3 be p-channel mosfets?. All n-channel mosfets in your circuit
No, all MUST be N-Channel. this is a famous configuration
I thought IR2104 is half bridge gate driver. one IR2104 can drive one motor. So your Schematic diagram of the H-Bridge DC motor driver have 2 IR2104. so you can drive 2 motors. right?
Maybe you can explain it like that. what twp chip does is that you don't need change the polarity of the supply to change the rotation direction
Make a video on H Bridge Inverter using TLP 250 or any other optocoupler. Can you suggest which mode is possible for the H Bridge or any Multilevel inverter, low side or high side is used in making simple H bridge inverter.
Okay, I will cover that if time and budget allows
hi, i build this board by using your pcb same components but failed to make it i don't know why can you guide me.
Sure, Did you design the PCB yourself?
Hi
If I want to control with raspberry pi, is it not enough ıf I give pvm1 and pwm2.
Can ı short circuit EN and GND. Do ı get a ground fault?
if you check the datasheet, it is already pulled down using a resistor inside the chip, so you can just leave it open. to disable the chip, you should apply Logic-1 to the EN
So is it okay if we leave the most pin blank? We dont need to put into action , ı understand it right ?
most pin blank? what does that mean? (OFF: PWM1=0 and PWM2 = 0) and ..... I have explained this to another user, check other comments also
Hi, I hope you are doing well. For clockwise rotation, Q1 and Q4 must take the pwm wave, while Q2 and Q3 must be off. But in your circuit, I think all the switches will take the pwm , because ir2104 products two depended pwm for high and low side. Am I right?
No. All Mosfets are N Channel. PWM=0 means OFF and PWM=something means rotation in that direction. No need to disable the chips. I have published another compact standalone device as well. Check the channel
Thank. I am going to control dc motor with that by using atmega32 in MPLAB IDE. I think I should make two PWM signals as pwm1 and pwm2, which, for example, pwm2 is NOT of pwm1. Am I right?
I'm enthusiastic to learn more from you. How can I keep in touch with you? Do you have telegram or whatsapp?
Yes you would need two separate PWM pins from the MCU (for example PWM-1 and PWM-2) that could work independently because the rotation speed of the left or right might not be necessarily equal. also, you should put one of the PWM outputs OFF where the other is generating pulses. if there is only one PWM, you should perform this using a switch as I did in a different project
Please can i ask what the purpose of using the diode in parallel with the gates mosfets resistors ? thanks and Nice work and video btw
You're welcome. As I mentioned in the video, you can read more in details in the article. Also you can order the PCB.
Great video and article. Right to the point. I am trying to find how I can order the PCB.
check below the article. There is a link where you can order the PCB. if You had any problem you can contact or chat with PCBWay
Hello Sir
Currently I am working on a project to control the speed of a DC motor (220VDC, 1000W). Currently I don't know how to make a driver circuit for the motor because the voltage and power of the motor are too large. I have an idea to follow the H bridge circuit. I hope Sir can guide and help me.
I use an Arduino board to drive this board. I have published another standalone design as well. check other videos
@@MyVanitar Can I make a driver circuit according to this video?
Yes, it's easy. Your first job is to watch the video completely and read the article, it's much beneficial than wasting the time on social media
I wanna use 4 DC motors, can i use 1 output for 2 motors?
Yes, you can use one output for as many parallel loads (motors) you like, just be careful about the current consumption. also check the latest video (so far). "A standalone Full Bridge DC Motor Driver"
Hello, where did you get that screw-terminal for connecting VCC,GND and the Motor? I've been looking for something like this for a long time, would really appreciate it (:
Don't worry, it is famous and easy to find, I don't remember the part number, check this video and article also: "Standalone Full Bridge DC Motor Driver"
@@MyVanitar OK thanks
In your circuit, I think will occur Braking in it when the motor is rotating with a PWM signal. Assuming the bridge is driving in one direction with a pwm, 1 is for mosfet turned on and 0 for mosfet turned off.
PWM2 will be settled to a continuous low level, then the motor will turn in one direction, forward or backward).
PWM1= high level of pwm PWM2 = 0
Q1 = 1 Q3=0
Q2= 0 Q4=1
When PWM1 signal has the PWM low level will occur Ranking in the low side, Q4 and Q2 will short circuit the motor terminals, the motor would work as a generator because his rotor will keep moving.
PWM1= low level of pwm PWM2 = 0
Q1 = 0 Q3=0
Q2= 1 Q4=1
As you can see, some kinetic energy will be wasted in the form of heat in the motor and mosfets. If the low side mosfets Q2 and Q4 were turned off during the pwm1 low level, the energy generated by the kinetic energy of the motor would be directed and stored to the power supply through the diodes.
Do you agree with that @MyVanitar?
Paulo, not agree :-). let's forget about technical aspects. Any short circuit in every pulse as you mentioned in such a PWM frequency (a few KHz) would be quite clear on the supply, because on my tests the motor supply and board supply and the Arduino supply are identical! IR2104 is a mosfet driver that you can build and have fun! diode are for protecting against reverse inductor currents.
Hello! I read in an article that using logic level mosfets that work at 5v (arduino output) and using bjt transistor as a controller to pre-amplify the voltage and current taking the mosfet to the saturation zone, how true is it? I am also looking for an alternative for bts7960
Hello, if you wanna build a motor driver, the best thing is to use driver chips, that's why are made for not using discrete components. 12V is everywhere because a power motor at least works with 12V, smaller ones are weak and not for power applications, probably small full h bridge chips are fine for them
Hello. I built this board but I have a problem: the input voltage is 24V but the output is only 0 to 12V to the motor. The PWM line goes from 0V to 5V. What I did wrong?
Hi. if the duty cycle of your PWM pulse is up to 50%, so it's correct: 24/2 = 12V, also your power supply should be able to deliver the current otherwise the voltage drops
@@MyVanitar The PWM is 100% (5V). The power supply is 2x12V UPS battery with enough amps ( If I power the motor directly from battery it works). If I connect only 1x12V battery the output is again 12V... It doesn't matter the input voltage... the output is 12V. I don't know what I did wrong. Some bad capacitor?
did you order my PCB or you built your own?
I ordered your PCB. I found the culprit. It was the C2 and C8 capacitor. They were "made in china" :)). Thanks for your response!
what do you mean by made in China? C2 and C8 are just ordinary ceramic capacitors
hi, why does it show error when pwm value is 255? When 254 is OK; but at 255 it gives under voltage
an Error? You might need to modify the code a bit, that's just for testing purpose
@@MyVanitar
thanks for your answer; but it is not possible to implement 100 %pwm with ir2104. I will be glad if you find a solution and share it with me. the video is so great
@@ATAS as I told you, it is not related to hardware or IR2104, you should not be hurry in electronic, just check the code and this "if" condition: if (UP.wasReleased() && PWM_Value < 250)
How can i add 2 buttons to stop the motor in both directions... one stop button for forward direction & second is for reverse direction?
My provided code is just a sample and for testing purposes. if you have an Arduino board or whatever hardware to generate PWM signals, you can write your own code. This circuit is the driver
@@MyVanitar thanx bro but i am not using arduino , i want to add only hardware
@@RehanKhan-nc6bf Yes, as I told you I used Arduino as an example to driver the board, otherwise you are free to use whatever hardware to control this
Thanks for video. I wonder "how could i check motor? Is it connected or not?" Thanks.
The only way is to measure the motor current. put a shunt resistor in series and measure the voltage over the shunt. if the motor works, it consumes something.
3:46 And a non conductive screw! Nylon screws usually
Not a screw, but a plastic washer
@@MyVanitar I meant a nylon bolt. If you use a metal bolt and a plastic washer it could still short out
whatever I say you make your assertion :-), no problem, use that bolt in your designs
Sir can I use 1uf polyester capacitor or electrolytic capacitor for boot strapping ? I doesn't get 1uf ceramic capacitor from local Market.
it's not ceramic. I think it is a multilayer one. you can use whatever type you like, but pay attention to the shape and pitch (distance between pins)
Thank you sir.
It is working forward and reverse
forward, reverse, stop. This video might be interesting for you as well: th-cam.com/video/lbVwRdweDYA/w-d-xo.html
I need information that if you have simulation in proteus plzz share with me how dc motor can be operated with h bridge by controlling forward and backward directions
I don't use Proteus simulation for these kinds of circuits
@@MyVanitar ok thanks sir
hello, would this work if i made it on veroboard instead of a pcb?
for low currents, yes
Hi,
How can I get the "JC_Button.h" library in the given coding for testing the H bridge motor driver board? Do you have a schematic file of the test circuit? Thank you.
Hi, my assumption for this project was that the users have some knowledge of Arduino to run this Driver. Please note that this is a motor driver and it needs PWM pulses at the input to control the motor. in the future, I may publish a standalone board. anyway, "JC_Button.h" library is there to use buttons to control the motor. Arduino has some default libraries and some can be installed externally. This library is external. You don't need to use my code and configuration, it is just an example to provide PWM signals to the board. (PWM1=pulse, PWM2=0, right rotation) (PWM1=0, PWM2=Pulse, left rotation) (PWM1=0, PWM2=0, OFF) , (EN=Logic-1, Driver ON) (EN: Logic-0, Driver OFF)
@@MyVanitar Thank you
current showing 0-1A. so how this can be 40A, can i increase current up to 20A using this circuit
excuse me?! what do you mean it should be 40A but it shows 1A?!
Can you make a video combination of h bridge and optical encoder to control DC motor rotating direction and speed
That's possible, however encoder on the motor it means you want to build a closed loop control system where you wanna have a feedback from the motor's behavior. I plan to publish something for the current sense check of the motor. in your case, the encoder might vary with the motor type. I can not offer a universal solution
nice
Thanks
Sorry but Its not keeping the torque identical that I'm interested in. Would like to know how this driver board performs under a sustained high current load. Simples!
the half bridge and full bridge configuration are the only methods that you can trust for stability and also low EMI
@@MyVanitar is this a full bridge?
Hi. is this high power motor driver? how can electronic elements can run 30A
Yes, it can. if the MOSFETs do not have a high RDS(on), then they would stand in high currents, because they won't generate heat. You must strengthen the high current carrying tracks using copper wires as well. that's why I have not covered them by the solder mask
Hi,
H-Bridge DC Motor Driver [40A, Power Mosfets]. Purchased from PCBWAY and want to use IRF450 for 170 volts kindly advice required change in board.
Regards,
I think you mean IRF540 because 450 has a different footprint. You should not short the body of MOSFETs (on the heatsink). pay attention to the voltages of the capacitors (load capacitor: C5, C6, C7). The supply voltage for the driver side must be only 12V. strengthen the high current tracks (by solder and copper wire) if you use the circuit for high currents.
c5,c6,c7 already changed to 200 volts, any change in gate resistor?
that's not a problem, even it is optional. Do you only have problems when you increase the load voltage?
yes after 50 volts
what happens then? something burns or similar?
nice video and article.👍
how is the performance compared to IBT-2(BTS7960)?
Thanks. You can mount a big heatsink on this and get higher currents. You can easily change Mosfets with other part numbers and drive higher voltage loads ... etc
Estoy tratando de hacer un puente h similar al BTS7960 con IR2110 y Nmos. El desafio es lograr el tiempo muerto por hardware utilizando puertas logicas, el BTS7960 lo tiene incluido en su logica interna, el IR2110 no lo tiene al igual que el circuito del video. Si conducen simultaneamente los dos mosfet de lado izquierdo o derecho se pueden quemar. Tambien el IBT-2 tiene un ic aislador de 8 fuffer y conexiones para PWM solo con dos entradas. Es un reto pero se puede hacer.
@@sebastiano6426 Hola! como vas con eso? yo también ando buscando alternativas para reemplazar el BTS7960 ya que no se consigue en mi país.
what can I substitute IR2104 with? online retailers in my country don't have it.
it's very famous. substitutes are not easier to find.
@@MyVanitar i've sent a private message to a retailer.
Thank you sir.
Most welcome
Can 1n5819 diodes handle high reverse currents?
They are not necessary at all. however, I added them to make a better design
Very nice and useful project. I want to build it.
Would it be ok if instead of the IR3205 MOSFET I would use the HSP6024A MOSFET?
Would it be better or worse? Thank you.
I couldn't find any datasheet of your MOSFET. So anyway check if the pins match (G-D-S) and how much is the RDs(on). Lower means lower heat dissipation. VDS is also important which must be higher than your input voltage or load voltage. I suggest you order the PCB directly from the link at the bottom of the article. The quality should be good, so don't go for cheapeas
@@MyVanitar Thank you. You can find the MOSFET on the LCSC(dot)com website. If you could take a look just to know if this would be ok I would be very grateful. I especially want to know if using this MOSFET would increase the output current capabilities of the PCB.
@@MyVanitar Here are the specifications for the HSP6024A MOSFET:
Vds: 60 V
Rds(ON): max 4.8 mΩ
Id: 200 A
Are these ok? Thank you.
It is good that you yourself grabbed that information otherwise I did not want to reply! These parameters are good, check the pinout if that is G-D-S
@@MyVanitar Thank you very much.
Hi There , been looking for a nice compact circuit like this, but i'm not an electronics expert so i had questions...
could this be used to drive leds or lasers even, or in my case a TEC (thermo electric conductor) or multiple . (12v 10a 136w ish x2)
i'm in the process of making my own driver board that also needs to have current sense , and temperature control to be used with an raspberry or logic board.
Furthermore, to be precise... i'm planning to use your simple half bridge design first since i don't need it to flip polarity, (but it would be a nice option)
it will have 3 + 2 temp sensors, 2 internal ammeters and 2 external, pwm for TEC and fan control, all this needs to be high frequency but low noise.
i know the pwm creates noise if hooked directly, but yours seem to switch with constant current am i right ?
Also, i'm wandering after doing a lot of reading and research... Since ill be using a high efficiency pc switch-mode power supply,
what would be the best option for me, ?
1. a insulated dual gate smart relay, x2, this can have a filter in b-tween gates
, and sensors etc.
2. a dual full bridge driver www.mouser.com/datasheet/2/389/l6207-954874.pdf (for example, ill need more current tho)
3. or the H-Bridge / half bridge, preferable with a fancy noise filter using ceramic polymer caps and the likes.
building my own full bridge is beyond my skills atm...
You asked a lot of questions. Yes you can driver anything that is at least 12V. This is not a constant current source. however you can supply your load with a constant current source, although it is not practical because when current increases (stays constant), the voltage decreases (compensates) and would be below 12V. if you don't want to change the polarity, half bridge is also fine. my first video in this channel is a half-bridge driver. you want to isolated the grounds? that is possible however I don't think load noise matters. PWM is injected to the Mosfet drivers. if your load would not stuck or it would not show such a risk, then you won't need current limit circuit. however, you can use the current limit outside of the board also, by non-invasive method (non contact)
You can also use the computer power supply yes. it provides a good 12V rail.
@@MyVanitar Thanks for your reply !
Well basically all the TEC controller boards i found out there are pretty complex,
as it comes to power delivery and temperature control duty cycle's, these are also used for laser diodes and cooling them.
most of them are 1 overengineered, 2 dont have the right options i need, and are like really expensive up like starting from $200
Since i want to learn more about automation and electronics, i decided to make my own project.
@@digivichi5071 I have not investigated about it, however it depends on the laser diode and its power. Most likely the driver is more or less a CC supply
@@MyVanitar sorry for so much questions, i was curious if the pwm signal is isolated from the load basicly.
Like Neil Worsfold say's b-low in the comments, ''Curious if the circuit could switch to motor regeneration when coastin''
i have read that certain motor and led/laser diode-controllers, also work for a tec if it has a coasting mode for heat management,
and optimal operating efficiency plus reverse polarity for cooling the unit itself. and so that it puts less noise on the feedback circuit...etc
in a full bridge the reverse current flow could be recycled, and parasitic loss should be mitigated, u would design it like a high voltage circuit where u insulate, the high switching frequencies , and the pwm switching noise from the circuit. switchmode is important, u dont want linear power, for these applications.
And one last note, most robotic's projects need dual drivers or more, for driving multiple things,
sorry for the wall of text and so. but thanks anyhow.. i will let u know if i ever complete my project and what i have come up with.
Hi
What is the frequency you used?
You are not bounded to any frequency. Just apply your PWM pulse to the input. I don't remember the Arduino PWM frequency.
Nice circuit. Does the IR2104 prevent shoot-through?
shoot through? can you explain in more detail?
@@MyVanitar Sure, no problem. Using your schematic as a reference, and using micro-seconds to mill-seconds as the time frame, if one were to want to switch the rotation of the motor from clockwise to counter-clockwise, or vice versa, there can be an issue with shoot-through, depending on timing.
So, if we switch direction, via a micro-controller, it will tell the MOSFET driver, to flip the gates to it's associated MOSFETs. Let's say we are talking about Q1 and Q2. Because MOSFETs do have wide turn on/off tolerances, usually in the micro-seconds, and sometime millisecond range, there will be a short period of time that when one MOSFET is turning on, say Q1, Q2 hasn't turned off all the way, which means you have a direct short to ground from the drain of Q1, going down the source of Q1, going into the drain of Q2, going through the source of Q2. The term for that is "shoot-through", because VCC shoots through directly to GND.
When designing an H-Bridge, this is one of the things that has to be taken into consideration to make sure that the MOSFETs don't have their lifespans significantly shortened, or that the motor or other inductive load doesn't get damaged... or the power supply itself.
The MOSFETs won't be damaged, however, it is better that you soft-start program such things (sudden direction change) using an MCU. The load (DC motor) "could be" at risk of mechanical damage because of a sudden reverse force. sometimes it is used for fast braking, however, not recommended :-)
@@MyVanitar fair enough. I know some drivers have dead time build into the IC to prevent this, but a lot of the time, it isn't obviously documented in the datasheet.
Yes, that's another advantage of using a driver, and most people amaze why I don't just drive a motor using a transistor and a single Mosfet, or sometimes just a Mosfet
which programm did you used for pcb design
Altium Designer
Hey what's the max output voltage ??

Yes, why not, what's the problem?
can I message you privately?
th-cam.com/video/uqnbgoxQfsE/w-d-xo.html
@@andyhartland1891 First of all, I liked your video, very good :-). This circuit has been tested by me and many users, so don't worry. Before you continue, make sure that you have not killed any MOSFET. so test them. then make sure that the ground PIN of both supplies is identical, which means the circuit has one ground.
You MUST inject a PWM pulse to one input and make another PWM=0 because the EN pin is identical for both Mosfet drivers, so once EN is active, you gonna play with PWM1 and PWM2. So to make it reverse just do vice versa. it must work if there is no other problem with your board. Also, You should have a basic load at the output all the time, to draw some mA of current.
@@MyVanitar Hi, thanks for the feedback :) I forgot to mention that I have both enable pins pulled high to keep them on all the time. May I ask if this a problem also? So if I read your guidance correctly, I need to make sure both inputs are always low, and then PWM one of them to activate the motor, but not 100% duty. Is that correct?
How is Q1,2,3,4 connected?
For the schematic and other details please check the article, if you mean the heatsink, they must not be connected to each other, you have to use a thermal pad and a specific plastic washer to electrically isolate each MOSFET body from the heatsink.
I need help, please.

But when "both" of the SD (ShutDown active Low) and Vin is powered with High Logic level (5V), IR21844S Low Side(LO) = 0V voltage and IR21844S High Side(HO) = 0.790V - 0.897V according to the Vin PWM signal variation Voltage is not supposed to be.
In a nutshell, IR21844S High Side(HO) is not bringing its voltage anymore when both SD (ShutDown active Low) and Vin is powered with High Logic level (5V) while IR21844S Low Side(LO) = 0V.
What I noticed I did wrong was that I did not connect the SD(ShutDown active Low) to any Logic Level(High or Low) which I know it shouldn't affect it because it's automatically connected to the GND according to its datasheet Functional Block Diagram but I only connected the Vin to High Logic Level(5V).
secondly, I used a Lead Acid battery 5V 4.5Ah (20hr) as my Logic Level.
Please Help me out...
did not understand your question, however, the chip is IR2104. You should power the chip with 12V. The load supply (motor for example) could be anything from 12V to 50V. in my test, the motor was also 12V.
Logic level is NOT identical with chip supply. logic could be 3.3V or 5V.
@@MyVanitar I know that Logic level is NOT identical with chip supply. logic could be 3.3V or 5V.
Yes, the chip is IR2104(8pins) but it's the same with IR2184(8pins) / IR21844S(14pins) according to the datasheet (They are both Half-bridge driver as although I know we have the Full-bridge driver which is different).
The Logic level 5V is meant for the EN pin so as to enable the chip to be active and also meant for the PMW's pin so as to switch the Half-Bridge from its initial position LO = 1 & HO = 0 to LO = 0 & HO = 1 so that the motor spins clockwise or counterclockwise accordingly to the chip powered.
Now, if the EN pin is HIGH (5v) and either PMW1 pin or PMW2 pin is HIGH(with PMW voltage), there should be Movement, right? Yes. which is equivalent to LO = 0 & HO = 1.
But my own case is different, if the EN pin is HIGH (5v) and either PMW1 pin or PMW2 pin is HIGH(with PMW voltage), there will not be Movement.
I traced where the problems are then I got to know it was from the Driver High Output(HO) having 0.790V which cannot drive the gate of the transistor and therefore the case is now LO = 0 & HO = 0.
Recall it was working normally before.
What I noticed I did wrong was that I forgot to connect the EN Pin to any Logic State(0V or 5V) but I only connected the PMW1 Pin to 5V.
secondly, I used a Lead Acid battery 5V 4.5Ah (20hr) as my Logic Level.
I hope you'd clearly understand the problems now.
Solutions Please I really need to get out of this problems
@@deewansonicengineering Hmmm, have you build my designed PCB or you are designing your own? in my design one EN pin decides about both chips. so for rotation change, you just need to disable the PWM of another channel and start the desired channel, one PWM channel at any time (check the Arduino code). PWM is also a few kHz square pulse, not a single pulse, are you sure they are generated correctly? The EN pin also should be kept high all the time as you see in the code. I have also provided an easy Arduino code for testing purposes which you can use. As a result, the circuit has been tested and I have not received any comment so far. Yours will work also don't worry. just check what you have done incorrectly. Also check for hardware mistakes, such as soldering. the oscilloscope also helps a lot. I don't know where you got the driver chips, but there are fakes in the market. as I always introduce a place to purchase original ones.
@@MyVanitar
The Testing Arduino code, is it in the article website?
it's now impressive, I'm feeling you are now understanding me.
I designed mine @PCB.
Yes, one EN is for both chips that's correct here also.
Yes, for rotation change, one PMW has to be disabled for the other to be enabled as Arduino code implies, that's correct here also.
The EN pin also should be kept high all the time as you see in the code. Yes.
just check what you have done incorrectly. was perfectly working before.
From my diagnoses, even if PMW signal is applied, the HIGH OUTPUT from the driver is not having any voltage to switch the Gate of the High Side MOSFET IRF3205.
From these perceptions and answers, I think all the Drivers are faulty right? This is kind of hard to believe.

Have you checked the article?, below the article there is a link where you can download the Gerbers or order 10pcs PCBs for a very cheap price. These projects are for non commercial purpose. so I'm afraid about the original PCB file

hi...PLEASE HELP,
I have a TC4429 Driver chip and a IRF4905 P channel mosfet.
I want to make a High side drive.
I have put a 1k resistor from gate to positive, 10k would be better.
the Source is direct to Positive and a 12 volt 1 Amp bulb is connected to drain and Gnd.
the TC4429 is run on 12V. i am feeding it with a PWM signal.
I cannot get the P channel mosfet to vary the output at all. it stays in the ON condition.
if i use an N channel mosfet it varies the output... in high side mode... but makes lots of heat!
i just want a decent High side driver ... i want 3 amps at 24v PWM output once i have a good circuit.
HHHEEELLLPP! :o)
What do you want to build that forces you to build a high side circuit?
@@MyVanitar A hydrogen electrolysys cell that has a steel case that is the negative. the negative is the ground for bolting onto the body of a vehicle which is negative earth. so i dont want to 'isolate' the main body from the negative of the battery.
so i need a posive that is being driven by PWM.... therefore a high side is needed. 24v at 3 amps. dont care what mosfets p or n... dont care what chip.... but need it the day befoe yesterday .. :o) ive got irf3205 N channels and ive got IRF4905 P channels. driver chips got TC4427 (low side driver) and TC4429(inverted High side driver) ... but it HAS to be that the Hydrogen cell Negative CASE is permanently Connected to the NEGATIVE of the battery.... so a PWM to feed the positive terminal of the hydrogen cell at 3 amps 24v... i cant get the P mosfet to turn on and off with the TC4429. im driving the chip with 12v and temporerily using 12v on the l;oad side also. (just a 12v car light+ car battery)
@@MyVanitar okay ive got an LED working..(i simply had drain and source wrong way round).... however its fine with chip running on 12 volts and mosfet also connected to 12 volts. But i want to have 24Volt output. but the chip cant run on 24v...they go BANG! i just found out.. :o)
but how do i drive the P mosfet if it is connected to 24v, but the chip can only run on 12V [ i dont think i get a high enough voltage on the gate] ive put a 10k resistor from the gate to the positive.
.... :o)
@@InterdimensionalWiz it is a bit hard to completely get what you mean because you know what's going on, not me. However, using a P Channel MOSFET I think fixes your problem, without using any special circuit or a high side driver.

Hello, this board work with 24V motores? Just plug and play?
I don't remember some values in the schematic. So just check the Mosfet VDS voltages (I think it was 50V), and capacitor voltages. I let you do this yourself and inform me here, just for you to learn :-)
@@MyVanitar Is 55V so i can connect 24V on the VCC to aplly to the motor i have?
@@wekker24 I told you check the capacitors also
@@MyVanitar 50V and 100V
@@wekker24 Yess, then you are fine. The voltage of the load (motor in your case) does not need to be equal to the driver chip. the driver works with 12V. so prepare 12V for that. Connect the load supply to 24V. Grounds are common. even the load side could be much higher if you change the capacitors with something with higher voltage
Will this work with 24V VCC?
24V Motor or 24V for the circuit Vcc?
@@MyVanitar I have 24V motor, will it work? And how much voltage do I have to give to mosfet drivers as well?
can I use it for nema34 stepper motor??
The short answer is No, because stepper Motor mechanism is different. it needs its own driver. I may cover it in future articles. it is not difficult
You need two of this circuit to run a stepper motor, one for each winding
İf we want made high voltage driver how we can made this ? İ mean 350 v dc Thank you.
Yes, you can. Why not. However because of your input voltage, you must replace some components. Change MOSFETs with something with higher voltage, such as IRF840, IRF540 or whatever. Majority of the Mosfets have the same pinout, including the ones which I mentioned. I mean G-D-S. Also low RDSon means lower temperature for the Mosfets. Second you must change the Motor connected capacitors with 400V rated capacitors. I don't remember the capacitor names, check the schematic. The value of the capacitors that are used to reduce the noise for the Motor are not critical, however for your case, make sure they are rated 400V. select the capacitors that fits the footprint on the PCB. That's it. Simple.
@@MyVanitar and can we use igbt ? Same footprint . İs it possible. Thank you

Hi sir, it is posible work like a bts7960 sir??
I checked your module, it claims 43A. In my opinion, it is impossible to get 43A out of this module with SMD components and no heatsink. This circuit uses TH MOSFETs so you can easily mount a heatsink on them. Just use some copper wires and solder on the exposed high current carrying tracks. The Voltage of the chip is 12V because MOSFETs need this voltage to be fully ON. PWM level could be 3.3V or 5V logic. Load voltage is above 12V and lower than 40V. However, it can be increased.
@@MyVanitar thank yo sir. Yes i want to make with dip version, i dont like smd version😅 because many bts are cracked🤣 voltage is 22-24v
