FAN7380 Half-Bridge Gate Driver February 2007 FAN7380 Half-Bridge Gate Driver Features Floating Channel Designed for Bootstrapping Operation to +600V Typically 90mA/180mA Sourcing/Sinking Current Driving Capability for Both Channels Common-Mode dv/dt Noise Canceling Circuit Extended Allowable Negative VS Swing to -9.8V for Signal Propagation at VCC=VBS=15V VCC & VBS Supply Range from 10V to 20V UVLO Functions for Both Channels TTL-Compatible Input Logic Threshold Levels Matched Propagation Delay Below 50ns Built-in 100ns Dead-Time Control Function Output in Phase with Input Signal 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 highside driver under high-dv/dt noise circumstances. An advanced level-shift circuit allows high-side gate driver operation up to VS=-9.8V (typical) 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 at 90mA/180mA, respectively, which is suitable for fluorescent / compact fluorescent lamp ballast applications and the systems that require low di/dt noise.
