ABSTRACT:
A device for protecting battery-powered semiconductor devices and the like against a reverse battery condition. During normal operation a charge pump charges the gate of a power MOSFET, turning the MOSFET on and providing a low-resistance power supply path from the battery to the load. If the battery is reversed, a depletion mode device shorts the gate and source of the MOSFET, turning it off and disconnecting the load from the battery.
