ABSTRACT:
An electrical power protection integrated circuit provides protection against reverse battery and overvoltage conditions that is particularly of value in automotive applications in which reverse battery and overvoltage conditions are commonplace. The electrical power protection integrated circuit device contains a reverse battery condition protection element, supplied either directly or indirectly from a battery power source, that protects against a reverse battery condition of the battery power source and an overvoltage protection element coupled to the reverse battery condition protection device that protects against an overvoltage condition of the battery power source and produces a protected power output that is isolated from both battery overvoltage and reverse battery voltage conditions. Additionally, the integrated circuit device can further produce an auxiliary protected power output that is isolated from reverse battery voltage conditions.
