MONOLITHIC CONTROLLER OF INDUCER INDUCER CURRENT CURRENT WITH INTEGRATED RECIRCULATION DIODE IN VERTICAL INTEGRATION TECHNOLOGY

摘要

The invention relates to a monolithic regulator of the excitation current of the inductor 1 of an alternator. The regulator comprises, on a substrate S of semiconductor material, a power transistor TP , a control circuit zone ZC, a recirculation diode zone ZD. Each zone of ZC, ZD is isolated from the substrate S by an independent isolation box 101, 201. The box 101 and the recirculation diode zone ZD having at least two diode junctions 101, 102 in cascade, capable of constituting a transistor parasitic tp the diode junction 102 likely to constitute the base emitter junction of the parasitic transistor tp is short-circuited by connection means 103, the parasitic transistor thus being suppressed. / P P Application to the production of integrated circuits for the regulation of the automobile alternator inductor. / P
