Description
The FAN7380 is a monolithic half-bridge gate drive IC for
MOSFETs and IGBTs, which operate up to +600V.
Fairchild’s high-voltage process and common-mode
noise canceling technique give 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 V_S=-9.8V (typical) for V_BS=15V. The
input logic level is compatible with standard TTL-series
logic gates. The internal shoot-through protection circuit
provides 100ns dead-time to prevent output switching
devices from both conduction during transition periods.
UVLO circuits for both channels prevent malfunction
when V_CC and V_BS are lower than the specified
threshold voltage. Output drivers typically source/sink at
90mA/180mA, respectively, which is suitable for
fluorescent / compact fluorescent lamp ballast
applications and the systems that require low di/dt noise.
