ABSTRACT:
A driver circuit (10), with a minimum number of interconnects between itself and a conventional output driver device (14), controls the normal on/off operation of the output driver device, and additionally senses various fault conditions within the output driver device. The driver circuit (10) also preferably shuts down the output driver device when the latter device begins to operate in a current limiting mode, and generates diagnostic signals which identify the type of fault condition that is sensed.
