Description
The FAN7382 is a monolithic half-bridge gate driver IC for
driving MOSFETs and IGBTs, which operate up to +600V.
Fairchild鈥檚 high voltage process and common-mode noise
canceling technique give stable operation of high-side driver
under high dv/dt noise circumstances. Advanced level shift
circuit allows high-side gate driver operation up to VS=-9.8
V(typ.) for VBS=15V. The input logic level is compatible
with standard TTL series logic gates. UVLO circuits for both
channels prevent malfunction when VCC and VBS are lower
than the specified threshold voltage. Output drivers typically
source/sink 350mA/650mA, respectively, which is suitable
for the applications such as fluorescent lamp ballast, PDP
scan driver, motor control, etc.
Typical Applications
鈥?PDP Scan Driver
鈥?Fluorescent Lamp Ballast
