Rev. 1.0.0 May 2008 FAN7388 3 Half-Bridge Gate-Drive IC Features Floating Channel for Bootstrap Operation to +600V Typically 350mA/650mA Sourcing/Sinking Current Driving Capability for All Channels 3 Half-Bridge Gate Driver Extended Allowable Negative VS Swing to -9.8V for Signal Propagation at VBS=15V Matched Propagation Delay Time Maximum: 50ns 3.3V and 5V Input Logic Compatible Built-in Shoot-Through Prevention Circuit for All Channels with 270ns Typical Dead Time Built-in Common Mode dv/dt Noise Canceling Circuit Built-in UVLO Functions for All Channels Applications 3-Phase Motor Inverter Driver Description The FAN7388 is a monolithic three half-bridge gate-drive IC designed for high-voltage, high-speed driving MOS- FETs and IGBTs operating up to +600V. Fairchild’s high-voltage process and common-mode noise canceling technique provide stable operation of high-side drivers 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 UVLO circuits prevent malfunction when VDD and VBS are lower than the specified threshold voltage. Output drivers typically source/sink 350mA/650mA, respectively, which is suitable for three-phase half-bridge applications in motor drive systems.
