Description
The FAN73832 is a half-bridge, gate-drive IC with shut-
down and programmable dead-time control functions for
driving MOSFETs and IGBTs, operating up to +600V.
Fairchild’s high-voltage process and common-mode
noise canceling technique provide stable operation of
high-side driver under high dv/dt noise circumstances.
An advanced level-shift circuit allows high-side gate
driver operation up to VS=-9.8V (typical) for VBS=15V.
The UVLO circuits for both channels prevent malfunction
when VDD and VBS are lower than the specified thresh-
old voltage.
Output drivers typically source/sink 350mA/650mA,
respectively, which is suitable for all kinds of half- and
full-bridge inverters.

Absolute Maximum Ratings
The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The
device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are
not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table defines the condi-
tions for actual device operation. TA=25°C unless otherwise specified.
