Abstract This paper describes an Integrated Circuit Fiber Optic Detector designed for control of DC loads in the several amperes range. ... The actual high current drive to the load is supplied through PNP power transistor Ql . The use of the high power PNP allows the aquot;hotaquot; (+12V) line to be switched rather than ... The Fiber Optic Detector must supply up to 500mA to Ql in order to be sure that it is saturated.
