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 1C 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 1C). This 1C 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.
