APPLICATION NOTE 636
Reverse-Current Circuitry Protection
Battery reversal can be fatal to portable equipment. However, numerous circuits can protect against the
backward installation of batteries and other overcurrent-causing conditions.

Battery-operated equipment is prone to the consequences of batteries installed backward, accidental short
circuits, and other types of careless use. The effects of a reversed battery are critical. Unfortunately, it is difficult
to guard against this situation.

To make equipment resistant to batteries installed backward, you must design either a mechanical block to
