That is pretty much how I am already doing it, using P/N MOSFETs and driving them with NPN/PNP BJTs. That isnt the problem. The problem is the MOSFETs need to provide the motor with 3V 6A, and I cannot saturate the MOSFETS at 3v as their threshold is 4V.
Okay, I can see how that would be a problem. In your original post, you said you could drive the motors at 5v. Wouldn’t solve your problem. You could even PWM the output to keep the current consumption within specs.
