| FAN7085_F085 High Side Gate Driver with Recharge FET March 2009 FAN7085_F085 High Side Gate Driver with Recharge FET • Qualified to AEC Q100 • Floating channel designed for bootstrap operation fully oper- ational up to 300V. • Tolerance to negative transient voltageon VS pin • dv/dt immune. • Gate drive supply range from 4.5V to 20V • Under-voltage lockout • CMOS Schmitt-triggered inputs with pull-down and pull-up • High side output out of phase with input Inverted input • Reset input • Internal recharge FET for bootstrap refresh • Diesel and gasoline injectors/valves • MOSFET-and IGBT high side driver applications The FAN7085_F085 is a high-side gate drive IC with reset input and built-in recharge FET. It is designed for high voltage and high speed driving of MOSFET or IGBT, which operates up to 300V. Fairchild's high-voltage process and common-mode noise cancellation technique provide stable operation in the high side driver under high-dV/dt noise circumstances. 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 250mA and 250mA. Built-in recharge FET to refresh bootstrap circuit is very useful for circuit topology requiring switches on low and high side of load.
