Hey,
my goal is to achieve an on/off switchable 12V voltage source meant for supplying some power mosfet gates out of 60V, controlled by a TTL output pin of a Attiny4, 85 or something like that.
This is my first approach, it's a n- and a p-channel mosfet switching a 12V zener diode.
Because the voltage is 60V I limited Vgs of the p-channel mosfet with a 12V zener diode but because of this only 12V out of the 60V drop at R8 and therefore a high current will flow through the n-channel mosfet, how is the right way to fix that? Should I just put an resistor in there?
Thanks!
