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 and high speed driving of MOSFET or IGBT, which operates up to 300V. ON Semiconductor'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 cir-cuits 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. • Floating channel designed for bootstrap operation fully operational up to 300V. • Tolerance to negative transient voltage on 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 SOIC-8 Typical Applications • Diesel and gasoline injectors/valves • MOSFET-and IGBT high side driver applications Ordering Information Device Package Operating Temp.
