- 5A continuous drain
- 20V drain to source voltage
- Ron = 45 mOhm @ 4A, 4.5V
Or we can use an NMOS power FET with a gate driver:

OR Gate:
- actually needs to be a NOR gate (inverted or), since a logic 1 at the output of the OR gate should turn off load switch
- able to take battery voltage on power supply, or pair with regulator that drops battery voltage to logic voltage
- 5V or 12V logic compatible (12V preferred)
- SOT package preferred
