Abstract

See full text

A device having an active reversal protection system is described. The system includes a pair of MOSFETs connected to parallel battery power sources. When the batteries in one of the power sources are improperly installed, the voltage delivered by that power source closes the gate of its associated MOSFET. In normal operation, the MOSFETs are connected to a microprocessor configured to operate the device. In a preferred embodiment, the device is a lighting device incorporating a light emitting diode that is driven by the MOSFETs.
