Description
The FAN73933 is a half-bridge, gate-drive IC with pro-
grammable 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 circum-
stances. 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.
