FAN73832 Half-Bridge Gate-Drive IC September 2006 FAN73832 Half-Bridge Gate-Drive IC Features Floating Channel for Bootstrap Operation to +600V Typically 350mA/650mA Sourcing/Sinking Current Driving Capability for Both Channels Extended Allowable Negative VS Swing to -9.8V for Signal Propagation at VDD=VBS=15V High-Side Output in Phase of IN Input Signal Built-in UVLO Functions for Both Channels Built-in Common-Mode dv/dt Noise Canceling Circuit Internal 400nsec Minimum Dead-Time at RDT=20KΩ Programmable Turn-on Delay-Time Control (Dead-Time) Description The FAN73832 is a half-bridge, gate-drive IC with shutdown and programmable dead-time control functions for driving MOSFETs and IGBTs, operating up to +600V. Fairchild’s high-voltage process and common-mode noise canceling technique provide stable operation of high-side 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 UVLO circuits for both channels 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 all kinds of half- and full-bridge inverters.
