FAN73933: 625V, 3.3/5V input logic compatible, 2.5/2.5A sink/source current, Half Bridge Gate-Drive IC with variable DT control

Description: The FAN73933 is a half-bridge, gate-drive IC with ...
  • The FAN73933 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.
    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.
    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, switching mode power supplies, induction heating, and high-power DC-DC converter applications.
