ational 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
Typical Applications
• Diesel and gasoline injectors/valves
• MOSFET-and IGBT high side driver applications
Description
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. 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.
