ABSTRACT:
Low voltage semiconductor devices are integrated monolithically with a high voltage semiconductor device on an electrically conductive substrate. The substrate forms an electrode of the high voltage device and is connected in use to the high voltage terminal of a power supply. The low voltage devices operate from a regulated low voltage supply, which is regulated with reference to the high voltage supply voltage, and not with reference to ground. This reduces the need to isolate the low voltage devices from the conductive substrate. An intelligent power switch circuit constructed in accordance with the invention is suitable for use in automotive and lighting applications.
