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. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

FPF2172
IntelliMAX™ Advanced Load Management
Features
Description
The FPF2172 is a load switch which combines the
functionality of the IntelliMAX™ series load switch with a
very low forward voltage drop Schottky barrier rectifier.
The integrated solution provides full protection to
systems and loads which may encounter large current
conditions in a very compact MLP 3 x 3 package. This
device contains a 0.125 Ω current-limited P-channel
MOSFET which can operate over an input voltage range
of 1.8-5.5 V. The Schottky diode acts as a barrier so
that no reverse current can flow when the MOSFET is
off and the output voltage is higher than the input
voltage. Switch control is by a logic input (ON) capable
of interfacing directly with low voltage control signals.
Each part contains thermal shutdown protection which
shuts off the switch to prevent damage to the part when
a continuous over-current condition causes excessive
heating.
