FAN7888 — 3 Half-Bridge Gate-Drive IC May 2008 FAN7888 3 Half-Bridge Gate-Drive IC Features Floating Channel for Bootstrap Operation to +200V Typically 350mA/650mA Sourcing/Sinking Current Description The FAN7888 is a monolithic three half-bridge gate-drive IC designed for high-voltage, high-speed driving MOSFETs and IGBTs operating up to +200V. 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. 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 Typically 270ns Dead Time Built-in Common Mode dv/dt Noise Canceling Circuit Built-in UVLO Functions for All Channels Applications 3-Phase Motor Inverter Driver 20-SOIC Ordering Information Part Number FAN7888M FAN7888MX Package 20-SOIC Operating Temperature Range -40°C to +125°C Packing Method Tube Tape & Reel All packag……
