Description
The FAN7392 is a monolithic high- and low-side gate
drive IC, that can drive high-speed MOSFETs and IGBTs
that operate up to +600V. It has a buffered output stage
with all NMOS transistors designed for high pulse current
driving capability and minimum cross-conduction. Fairch-
ild’s high-voltage process and common-mode noise can-
celing techniques provide stable operation of the high-
side driver under high dv/dt noise circumstances. An
advanced level-shift circuit offers high-side gate driver
operation up to V S =-9.8V (typical) for V BS =15V. Logic
inputs are compatible with standard CMOS or LSTTL
output, down to 3.3V logic. The UVLO circuit prevents
malfunction when V CC and V BS are lower than the speci-
fied threshold voltage. The high-current and low-output
voltage drop feature makes this device suitable for half-
and full-bridge inverters, like switching-mode power sup-
ply and high-power DC-DC converter applications.
