FAN7380 − Half Bridge Gate Driver

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. Advanced level shift circuit allows high-side gate driver operation up to V_S = -9.8V (typ.) 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 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.
