If I want to drive a generic N channel FET, say an Infineon IPB70N10SL-16. This is a 100V, 70 amp, 16mOhm RDSonn part. If I use it as a high side switch to a 12 volt source, I know that I need my gate voltage to be higher than the 12 volt rail, but what I don't know is how to calculate/find how much current I'll need to drive the gate. Any help is appreciated.
