FAN7393 Half-Bridge Gate Drive IC December 2009 FAN7393 Half-Bridge Gate Drive IC Features „ Floating Channel for Bootstrap Operation to +600V „ Typically 2.5A/2.5A Sourcing/Sinking Current Driving Description The FAN7393 is a half-bridge, gate-drive IC with shutdown and programmable dead-time control functions that can drive high-speed MOSFETs and IGBTs operating up to +600V. It has a buffered output stage with all NMOS transistors designed for high-pulse-current driving capability and minimum cross-conduction. Fairchild’s high-voltage process and common-mode noise canceling techniques provide stable operation of the high-side driver under high dv/dt noise circumstances. An advanced level-shift circuit offers high-side gate driver operation up to VS=-9.8V (typical) for VBS=15V. [ ... ]
