FAN7380
Features
Half-Bridge Gate Driver
(SOURCING/SINKING : 90mA/180mA)
Description
The FAN7380 is a monolithic half-bridge gate driver IC for
MOSFETs and IGBTs, which operate up to +600V. Fair-
child鈥檚 high voltage process and common-mode noise can-
celing 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=-
9.8V(typ.) for VBS=15V. The input logic level is compatible
with standard TTL series logic gates. The internal shoot-
through protection circuit provides 100nsec dead-time to
prevent output switching devices from both conduction dur-
ing transition periods. UVLO circuits for both channels pre-
vent malfunction when VCC and VBS are lower than the
specified threshold voltage. Output drivers typically source/
sink 90mA/180mA, respectively, which is suitable for the
applications such as fluorescent/compact fluorescent lamp
ballast applications and the systems that require low di/dt
noise.
