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
www.onsemi.com.

email any questions regarding the system integration to

FAN54151 – High Current Charging Switch with Protection
April 2016
FAN54151
High Current Charging Switch with Protection
Features
Integrated Back-to-Back Common Source
N-channel MOSFETs with combined R
ON
= 17 mΩ
Description
The FAN54151 is a low loss, high current, I C controlled
switch.
Built in protection monitors the ICs input and output for
over- and under-voltage as well as over- and under-
current. The system protection is provided by controlling
the gate voltages of a pair of N-channel MOSFETs to
ensure that the output stays within a safe operating
range. If a fault is detected, the FAN54151 will turn off
the N-channel FETs and notify the host system via
configurable interrupts.
Additionally, the FAN54151 includes an integrated
temperature sensor and battery cell voltage monitor that
are trademarks of Semiconductor Components Industries, LLC dba ON Semiconductor or its subsidiaries in the United States and/or other countries.
