FAN73933MX

The FAN73933MX is a half-bridge Gate Drive IC with 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. High-voltage process and common-mode noise cancelling 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. The UVLO circuit prevents malfunction when VDD and VBS are lower than the specified threshold voltage. The high-current and low-output voltage drop feature makes this device suitable for diverse half- and full-bridge inverters, motor drive inverters and high-power DC-DC converter applications.
