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 FAN3111 1A gate driver is designed to drive an N-
channel enhancement-mode MOSFET in low-side
switching applications.
Two input options are offered: FAN3111C has dual
CMOS inputs with thresholds referenced to V
DD
for use
with PWM controllers and other input-signal sources
that operate from the same supply voltage as the driver.
For use with low-voltage controllers and other input-
signal sources that operate from a lower supply voltage
than the driver, that supply voltage may also be used as
the reference for the input thresholds of the FAN3111E.
This driver has a single, non-inverting, low-voltage input
plus a DC input V
XREF
for an external reference voltage
in the range 2 to 5 V.
The FAN3111 is available in a lead-free finish industry-
