note=when VUSB is not present, the gate is pulled low to allow powering the device using the battery (bypassing the body diode). when VUSB is present, the gate is tied high, disable the transistor. the body diode prevents VUSB to mis-charge the battery.

note=when VUSB is not present, the gate is pulled low to allow powering the device using the battery (bypassing the body diode). when VUSB is present, the gate is tied high, disable the transistor. the body diode prevents VUSB to mis-charge the battery. it also protects from reversing the polarity on the battery connector.
