SMD MOSFET to power down my SMD H-Bridge

dc42:
Perhaps PMV48XP then?

Thanks! Here's what I came up with...
Is R1 needed? I usually put something like that to make sure the motor is off while the Arduino boots up.
So nothing is needed between the Arduino pin and the gate of the BS1338?
Sure appritiate all the help!

I'll be glad to go this route rather than just a relay.
