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.
