Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com 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 Semiconductors 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.

The FPF1039 consists of 21 m at V =4.5 V IN slew-rate controlled low-impedance MOSFET switch (21 m typical) and other integrated analog features. 37 m at V =1.8 V IN The slew-rate controlled turn-on characteristic prevents 75 m at V =1.2 V IN inrush current and the resulting excessive voltage droop on power rails. Slew Rate / Inrush Control with t : 2.7 ms (Typical) R This device has exceptionally low shutdown current 3.5 A Maximum Continuous Current Capability drain (<1 A maximum) that facilitates compliance in Output Capacitor Discharge Function low standby power applications. The input voltage range operates from 1.2 V to 5.5 V DC to support a wide range Low <1 A Shutdown Current of applications in consumer, optical, medical, storage, ESD Protected: Above 8 kV HBM, 1.5 kV CDM portable, and industrial device power management. GPIO / CMOS-Compatible Enable Circuitry Switch control is managed by a logic input (active HIGH) capable of interfacing directly with low-voltage control signal / GPIO with no external pull-up required. The Applications device is packaged in advanced fully green 1mm x1.5 mm Wafer-Level Chip-Scale Packaging (WLCSP) HDD, Storage, and Solid-State Memory Devices providing excellent thermal conductivity, small footprint, Portable Media Devices, UMPC, Tablets, MIDs and low electrical resistance for wider application usage.
