The FAN7380 is a monolithic half-bridge gate-driver IC for MOSFETs and IGBTs that operate up to +600V. 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 100ns 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 and 180 mA, respectively, which is suitable for fluorescent/compact fluorescent lamp ballast applications and systems requiring low di/dt noise.
