sam.moshiri Posted September 5, 2020 Report Share Posted September 5, 2020 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 braking 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.

Guy Shemesh Posted September 5, 2020 Report Share Posted September 5, 2020 It looks very nice, I also like the layout and the fact you used polygon pours on both sides. I think one improvement would be to make edge plating on the sides, it helps dissipate the heat off the main board. If you can add schematics to the post that would also be interesting to see.

Jane Lam Posted October 29, 2020 Report Share Posted October 29, 2020 which PCB manufacturer do you choose? I compare PCBway and NextPCB, it's cheaper on NextPCB, And they give a $10(no limits) coupon to me, you could have a try. Quote Link to comment Share on other sites More sharing options...
