Abstract
A load driver circuit has an output transistor driving the load, with a protective circuit that, when enabled, turns off the output transistor to protect it from high current levels. A delay circuit, which responds to abnormal load conditions after the output transistor has been on for a brief interval, enables the protective circuit to cause turn-off of the output transistor.
