Description
The FAN73932 is a half-bridge, gate-drive IC with shut-
down and dead-time functions which can drive high-
speed MOSFETs and IGBTs that operate 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 all kinds of half- and full-
bridge inverters, like motor drive inverter, switching
mode power supply, induction heating, and high-power
DC-DC converter applications.
