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
operate 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 malfunction when VCC and VBS
are lower than the specified threshold voltage. Combined pin
function for dead time adjustment and reset shutdown enable
this IC to be packaged in a space saving SO 8L NB Package.
Minimum source and sink current capability of output driver is
250mA and 500mA respectively, which is suitable for automo-
tive DC-DC converters and half and full bridge motor control
applications.
