neurokinetik -> how's the battery life with the T0-220 FETs? Is it much shorter?
Both P and N channel FETs must be logic level ones right?

I haven't noticed any battery life differences, and I really didn't expect to see any. Both P and N channel FETs are logic level.
As for 12V damaging the motor, well, for my drag car that wouldn't be a concern. The 180 motor is designed to run on 6-12V, and that's straight from Mabuchi. Plus it only really has to last about 5 seconds or less...

OK, then here is the circuit that has been tested, and does work. Note that Pin 1 on IC5 and IC6 is the same connection, so as long as you tie the sources of both IRL3705Ns together, only one wire needs to be run to the board to make that connection, hence 7 wires needed instead of 8.
