#67906 - RE: LOW-SIDE MOSFET DRIVER Responding to: ???'s previous message |
I suspect that you could realize a very effective driver for an N-channel MOSFET by using a PNP transistor to pull the gate to +12 volts for the ON condition and then bias the part OFF with a suitable resistor to ground from the gate For efficiency, you need to turn mosfets on and off quickly, to turn it on, use a PNP transistor to charge the mosfet gate very quickly, to turn it off, never use a resistor because it is slow, always use NPN transistor to ground.
