Description
The FAN7380 is a monolithic half-bridge gate-drive IC for
MOSFETs and IGBTs that operate up to +600 V.
Fairchild’s high-voltage process and common-mode
noise cancelling technique provide stable operation of
high-side driver under high-dv/dt noise circumstances.
An advanced level-shift circuit allows high-side gate
driver operation up to VS=-9.8 V (typical) for VBS=15 V.
The input logic level is compatible with standard TTL-
series logic gates. The internal shoot-through protection
circuit provides 100 ns dead-time to prevent output
switching devices from both conducting during transition
periods. UVLO circuits for both channels prevent
malfunction when VCC and VBS are lower than the
specified threshold voltage. Output drivers typically
source / sink at 90 mA / 180 mA, respectively, which is
suitable for fluorescent / compact fluorescent lamp
ballast applications and systems requiring low di/dt noise.
