Description

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 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.
