It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google (who would have thunk it ! ) or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.

No the mosfets do not have a driver, it gets signal from processor

Schematics and details for the current unit ?

Present MOSFET that is in there ?

Actual application you want to upgrade for ?

It is easy to stick a jet engine in a Mini but without context you would be on your own.  :smiley-eek-blue:
