电机驱动icFAN7888 3 Half-Bridge Gate-Drive IC Features Description . Floating Channel for Bootstrap Operation to +200V The FAN7888 is a monolithic three half-bridge gate-drive Typically 350 mA 1 650 mA Sourcing/Sinking Current IC designed for high-voltage, high-speed driving MOS- Driving Capability for All Channels FETs and IGBTs operating up to +200 V. .3 Half-Bridge Gate Driver Fairchild's high-voltage process and common-mode Extended Allowable Negative Vs Swing to -9.8 V for noise canceling technique provide stable operation of Signal Propagation at Vgs=15 V high-side drivers under high-dv/dt noise circumstances. Matched Propagation Delay Time Maximum: 50 ns An advanced level-shift circuit allows high-side gate .3.3 V and 5 V Input Logic Compatible driver operation up to Vs=-9.8 V (typical) for VBs=15 V. Built-in Shoot-Through Prevention Circuit for All The UVLO circuits prevent malfunction when VDD and Channels with 270 ns Typical Dead Time VBs are lower than the specified threshold voltage. Built-in Common Mode dv/dt Noise Canceling Circuit Output drivers typically source/sink 350 mA 1 650 mA, Built-in UVLO Functions for All Channels respectively, which is suitable for three-phase half-bridge applications in motor drive systems. Applications .3-Phase Motor Inverter Driver 20-SOIC
