Of course, I would use MOSFET > drivers.. but I have never used them before, --------------------------------------- I use IRLZ Mosfets (ie IRLZ24) - logic level switched HexFets - switching 12 volts, using just a 100 ohm resistor from the port pin to the gate (don't need drivers). They have a very low Rds (0.1 ohms), and are rated at 60volt / 17 amps.
