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

FAN7384 — Half-Bridge Gate-Drive IC
July 2012
FAN7384
Half-Bridge Gate-Drive IC
Features
Floating Channel for Bootstrap Operation to +600V
Typically 250mA/500mA Sourcing/Sinking Current
Description
The FAN7384 is a monolithic half-bridge gate-drive IC
designed for high voltage, high speed 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 drivers 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 prevent malfunction when V
DD
and
V
BS
are lower than the specified threshold voltage.
Output drivers typically source/sink 250mA/500mA,
respectively, which is suitable for half-bridge and full-
bridge applications in motor drive systems.
Driving Capability for Both Channels
Extended Allowable Negative V
