ABSTRACT:
An apparatus conducts current through a two terminal inductive load. The apparatus has a first conduction path, from a first supply voltage to one terminal of the inductive load and a second conduction path from the second terminal of the inductive load to a second supply voltage. The first conduction path includes a switching device that is controlled by a field-effect transistor having a gate terminal, second terminal, and third terminal. The gate terminal of the field-effect transistor is coupled to a reference voltage. The voltage at the second terminal of the field-effect transistor increases when the voltage at the field-effect transistor's third terminal increases.
