SEMICONDUCTOR SWITCHING CIRCUIT ESPECIALLY FOR DRIVING INDUCTIVE LOADS, FOR FAST SWITCHING LARGE CURRENT FAST

摘要

A semiconductor switch comprising a lateral DMOS (QMOS) and a lateral IGT (QIG) both of which can be fabricated in a monolithic integrated circuit. In operation the lateral DMOS stays on (VGI) while the lateral IGT (VG) is switched off in order to reduce turn off power dissipation.
