Half-Bridge Gate-Driver

The FAN7380 is a monolithic half-bridge gate-drive IC for MOSFETs and IGBTs, which operate up to +600V. onsemi'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 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 100ns dead-time to prevent output switching devices from both conduction 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 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.
