Hi There,

I have a kinda stupid question. I haven't worked with MOSFETs for years
and I have a rather simple problem: I want to power cycle a secondary
client device by an active signal coming from a comparator. And in defalt
case the, the device should always have power. I want to switch it using a
MOSFET. Now my idea:
I take a depletion mode mosfet (normally closed) that has very little
resistance between source and drain (any type recoimmendations?). Now can
I use a P-channel type and connect the gate to the comparator's output and
it will keep S & D low ohm-ish until the comparator becomes active (to
reset the client devcice)? Am I thinking right here? Any assistance would
be appreciated! Thank you!!!


Will LTspice model that?
