I'm doing a project where a PIC output pin supplies power to an on-board peripheral chip. When the device is turned on by the user, power is supplied to to the peripheral chip. When the device is turned off by the user, power is removed. The peripheral chip only draws about 5uA so there's no issue with steady current demand.
My concern is the .1uF decoupling capacitor required on the peripheral chip's Vdd pin. Will the the charging and discharging of that decoupling capacitor through the PIC's output pin eventually damage the PIC?
I've actually been working with the device for some time with no issue. I'm just wondering if I really should change that. I'd rather not if I don't have to.
