Description

The FAN7080_GF085 is a half-bridge gate drive IC with reset

input and adjustable dead time control. It is designed for high

voltage and high speed driving of MOSFET or IGBT, which

operates up to 600V. Fairchild's high-voltage process and com-

mon-mode noise cancellation technique provide 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 cir-

cuits for both channels prevent from malfunction when VCC and

VBS are lower than the specified threshold voltage. Combined

pin function for dead time adjustment and reset shutdown make

this IC packaged with space saving SOIC-8 Package. Minimum

source and sink current capability of output driver is 250mA and

500mA respectively, which is suitable for junction box applica-

tion and half and full bridge application in the motor drive sys-

tem.
