ABSTRACT:
A transistor circuit (50) in accordance with the invention includes a bipolar transistor (52) having a base and an emitter and collector coupled to a source of variable DC potential (54); an electrical load (22) coupled between the source of variable DC potential and one of the emitter and collector; a limit current generator (60), responsive to the variable DC potential, for producing a signal specifying a current limit for operating the transistor as a function of the sensed potential; a current sensor (64), coupled to the transistor circuit, for sensing current flow to the load from the source of DC potential; and a comparator (62), responsive to the current limit and the current flow to the load, for providing on an output a turnoff signal to the base of the transistor when the current flow exceeds the current limit.
