Description
The FAN7083_F085 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.
Fairchild's highvoltage process and common-mode noise cancellation technique provide stable operation in the high side driver under high-dV/dt noise circumstances.
An advanced level-shift circuit allows high-side gate driver operation up to VS=-5V (typical) at VBS=15V.
Logic input is compatible with standard CMOS outputs.
The UVLO circuits prevent from malfunction when VCC and VBS are lower than the specified threshold voltage.
It is available with space saving SOIC-8 Package.
Minimum source and sink current capability of output driver is 200mA and 400mA respectively, which is suitable for magetic-and piezo type injectors and general MOSFET/IGBT based high side driver applications.
