FAN7085-GF085 High Side Gate Driver with Recharge FET FAN7085-GF085 High Side Gate Driver with Recharge FET Features Description Qualified to AEC Q100 The FAN7085-GF085 is a high-side gate drive IC with reset input and built-in recharge FET. It is designed for high voltage Floating channel designed for bootstrap operation fully oper- and high speed driving of MOSFET or IGBT, which operates up ational up to 300V. to 300V. ON Semiconductor's high-voltage process and Tolerance to negative transient voltage on VS pin common-mode noise cancellation technique provide stable operation in the high side driver under high-dV/dt noise dv/dt immune. circumstances. Logic input is compatible with standard CMOS Gate drive supply range from 4.5V to 20V outputs. The UVLO cir-cuits prevent from malfunction when VCC and VBS are lower than the specified threshold voltage. It Under-voltage lockout is available with space saving SOIC-8 Package. Minimum CMOS Schmitt-triggered inputs with pull-down and pull-up source and sink current capability of output driver is 250mA and 250mA. Built-in recharge FET to refresh bootstrap circuit is High side output out of phase with input (Inverted input) very useful for circuit topology requiring switches on low and Reset input high side of load. Internal recharge FET for bootstrap refresh SOIC-8 Typical Applications Diesel and gasoline injectors/valves MOSFET-and IGBT high side driver applications Ordering Information Operating Device Package Temp.
