WebbThe P-MOSFET I'm using has a max Vgs of +-20V. The battery is of lead acid type, and should never exceed 15V even while being charged, but to be on the safe side, I'd like to protect the gate, perhaps keeping Vgs between -12V and -10V. Vin is around 18V when the device is plugged in, floating otherwise.
