Hello.
I would like to drive a relay 12 V, with a pic micro 0-3.3V, using a N-channel high side mosfet.
I tried different values of R and put NPN transistor but I couldn't manage, since I can not find a solution to have a switching voltage on gate that is higher (I guess) then +V, in order to switch on and off the mosfet.
Any suggestion or example circuit will be very appreciated.
Many thanks
