Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at

FAN73832
Features
Half-Bridge Gate-Drive IC
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 V
S
=-9.8V (typical) for V
BS
=15V.
The UVLO circuits for both channels prevent malfunction
when V
DD
and V
BS
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.
Floating Channel for Bootstrap Operation to +600V
