ABSTRACT:
A high efficiency current limit circuit comprises a current sensor, a control unit responsive to the current sensor for providing a control signal to a solid-state series pass element which limits load current. A thermal safety circuit provides overtemperature circuit protection. Together, the current limit circuit and thermal safety circuit provide continuous short circuit protection (of indefinite time duration) with automatic recovery upon removal of the short.
