Abstract
A high power microelectronic switching circuit is interfaced with a fiberoptic data link, whereby inductive or resistive loads up to 20 amperes are switched, with a forward voltage drop of less than one volt. An input signal of one-half milliwatt is passed to the gate of a V-MOS FET power device, which drives a PNP output transistor to switch a power supply to a circuit load.
