Hi Everyone,
I am currently working on a project and am developing a charging circuit. My goal is that whenever I plug the charger into my circuit, the rest of the circuit cuts power and the battery charges. I have done some preliminary research and have come with using a depletion type n-channel mosfet at the positive source of the battery so that when the charge plugs in, positive end is applied to the gate of the mosfet and the power from the battery is cut off. I have the following mosfet in mind:

The charger will be from a USB outlet so it will supply 5V @ 500 mA. If anyone has any suggestions I would appreciate it, and I am open to any questions as well. Thank you!
