It's standard practise on schematics to replace the device being driven with RL.
It might not be driving a motor, it could be a latching relay coil or even a speaker.
The only thing I would change is to put a 1K between each 7204 gate and the corresponding drains.
Why do you suggest that?
That makes sense.Because the 12V is too close to the absolute max ratings. I might even make it a 2K.
The internal MOSFET diodes should provide some protection but I'd add some protection diodes if I had any doubts.And there's just something creepy about hooking a gate (all exposed like) to a motor winding, or any exposed I/O pin for that matter. Since these are FETs, do you think someone should tell him about ESD and proper handling and all that?
