Hi all,
I'm using 7 P-channel mosfets to switch different loads using 1 microcontroller on an electrical power and distribution system. My circuit is as follows for each of the 7 Mosfets.
Gate: through a resistor to ground on microcontroller and through a High value (600 kilaohms)
Drain: to load
Source: I/O line from microcontroller and input power
So all the gates are interconnected to the ground on the cpu
The problem I'm having is that when I turn one mosfet on all the mosfets turn on and I can't figure out why. I am unable to use N-Channel mosfets. Any help on this matter would be very very appreciated
