Hi there- I'm familiar with p-chan mosfets, but I've only ever used them with dedicated drivers or 12-15V source.
I'm looking to use a p-chan mosfet to enable one MCU to control power to a secondary MCU (see attached).
Will this switch adequately? i.e., will the pull up resistor from gate to source work okay at just 3.3V? The plan is obviously for the secondary MCU to turn ON when the primary MCU pulls it's output LOW.
thanks!
