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. 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 magnetic-and piezo type injec­tors and general MOSFET/IGBT based high side driver applica­tions.
