The chip is rated at 3A continuous, but I'd like to use it to drive a coil (electromagnet actually) at 6A continuous in either direction. The specs say I can go that high for a burst, but I want it to be able to do 6A for a prolonged time. I've heard that paralleling can get me a little higher (4A), but I was hoping instead to feed a mosfet from the out pins of the LMD18201 to amplify the current. Problem is I don't know how to account for the directional shifting when PWM goes reverse. Any ideas? Thanks.
