I need to control a 12V 100A DC motor and I was thinking of using this circuit, I saw many post and application notes that talk about parallelizing MOSFETs but I did not see any circuit using MOSFET drivers or in H-Bridge, my question is if this circuit is ok

BTW: The mosfet that I will use are IRF1404, Rds=0.004 ohm

Edited: sorry I avoid the circuit

    High side N channel ones eh? – Paul Uszak Apr 19 '21 at 13:26

    I have been playing with BTN7971B MOSFET H-bridge driveres. I also experimented with paralleling two L298N drivers and found no problems. Of course there are many other MOSFET H-bridge drivers.

  • I'm sure that you appreciate your motor is 1.2kW - the size of a professional circular saw. And that's what it can do. Is there any motor /voltage feedback elsewhere? Running offa what? Battery? Fuse? Can IN1 and IN2 both be the same state as that catches many out here? – Paul Uszak Apr 19 '21 at 13:43
  • But IRF1404 can already do 200+A continuous, so there is no need to parallel two IRF1404 for bigger current. – tlfong01 Apr 20 '21 at 14:49
