A description is given of a fully protected bipolar MOSFET controller which is designed to drive and protect current-sensing or standard DMOS (double-diffused metal-oxide-semiconductor) field-effect transistors in either high-side or low-side configurations. The IC is designed for use in automotive environments, and therefore protects both the discrete MOSFET and the driver IC from overvoltage, overtemperature, and short-circuit conditions. The circuit operates from 4.5 to 28 V, draws 20- mu A off-state current, and gives diagnostic feedback via an error pin.
