A high reliability and low loss 3-phase gate driver IC with a novel soft gate drive circuit for 42V motor generator system

摘要

We have developed a three-phase driver IC for the 42V motor generator automotive system using a 100V class SOI isolated 0.5μm three metal layer bipolar CMOS LDMOS process SOIPIC (SOI Intellectual Property Power IC). This IC has a soft gate drive function with a new concept of loss minimization for a low on-state-resistance 100V 500A class trench power MOSFET.
