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

Description
The FAN73711 is a monolithic high-side gate-drive IC
that can drive high-speed MOSFETs and IGBTs operat-
ing up to +600 V. 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 V

is lower than the specified threshold voltage.
The high-current and low-output voltage-drop feature
makes this device suitable as a sustain and energy-
recovery circuit switch driver in plasma display panel,
motor drive inverter, switching power supply, and high-
