FAN7081-GF085 High Side Gate Driver FAN7081-GF085 Description High Side Gate The FAN7081 -GF085 is a high-side gate drive IC designed for Driver high voltage and high speed driving of MOSFET or IGBT, which operates up to 600V. ON Semiconductor's high-voltage process and com-mon-mode noise cancellation technique provide Features stable opera-tion 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 Qualified to AEC Q100 cir-cuits prevent from malfunction when VCC and VBS are lower than the specified threshold voltage. It is available with Floating channel designed for bootstrap operation up fully space saving SOIC-8 Package. Minimum source and sink operational to + 600V current capability of output driver is 250mA and 500mA Tolerance to negative transient voltage on VS pin respectively, which is suitable for magnetic- and piezo type injectors and gen-eral MOSFET/IGBT based high side driver dV/dt immune. applications. Gate drive supply range from 10V to 20V Under-voltage lockout SOIC-8 CMOS Schmit-triggered inputs with pull-up High side output out of phase with input (Inverted input) Typical Applications Diesel and gasoline Injectors/Valves MOSFET-and IGBT high side driver applications Ordering Information Operating Device Package Temp.
