General 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 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.
