Description
The FAN7083-GF085 is a high-side gate drive IC with reset input. It is designed for high voltage and high speed driving of MOSFET or IGBT, which operates up to 600V. ON Semiconductor 's high-voltage process and common-mode noise cancellation tech-nique provide stable operation in the high side driver under high-dv/dt noise circumstances. An advanced level-shift circuit allows high-side gate driver operat ion up to VS=-5V (typical) at VBS=15V. Logic input is compatible with standard CMOS out -puts. The UVLO circuits p revent from malfunction when VCC and VBS are lower than the specified threshold voltage. It is available with space saving of ou tput driver is 200mA and 400mA respectively, which is suit able for magnetic-and piezo type injec-tors and general MOSFET/IGBT based high side driver applica-tions.
