An SOI based integrated gate-drivers for automotive application

This paper presents our recent development of an ASIC for automotive application. With the progress of automotive electronics, there is increasing need for high temperature and high voltage operation. The ASIC for the EPS applications was integrated with a boost gate driver, three-phase inverter drivers and their components. The ASIC was designed and fabricated using SOI-BiCD process which can operate at the maximum voltage of 80V and at temperature from -40°C to 175°C.
