FPF1038 Low On-Resistance, Slew-Rate-Controlled Load Switch Features Description The FPF1038 advanced load-management switch target applications requiring a highly integrated solution for disconnecting loads powered from DC power rail (<6 V) with stringent shutdown current targets and high load capacitances (up to 200 µF). The FPF1038 consists of slew-rate controlled low-impedance MOSFET switch (21 mΩ typical) and other integrated analog features. The slew-rate controlled turn-on characteristic prevents inrush current and the resulting excessive voltage droop on power rails. 1.2 V to 5.5 V Input Voltage Operating Range Typical RON: − 20 mΩ at VIN=5.5 V − 21 mΩ at VIN=4.5 V − 37 mΩ at VIN=1.8 V − 75 mΩ at VIN=1.2 V Slew Rate / Inrush Control with tR: 2.7 ms (Typical) 3 A Maximum Continuous Current Capability Low <1 µA Shutdown Current ESD Protected: Above 8 kV HBM, 1.5 kV CDM GPIO / CMOS-Compatible Enable Circuitry Applications HDD, Storage, and Solid-State Memory Devices Portable Media Devices, UMPC, Tablets, MIDs Wireless LAN Cards and Modules These devices have exceptionally low shutdown current drain (<1 µA maximum) that facilitates compliance in low standby power applications. The input voltage range operates from 1.2 V to 5.5 V DC to support a wide range of applications in consumer, optical, medical, storage, portable, and industrial device power management. 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 device is packaged in advanced fully “green” 1mm x1.5 mm Wafer-Level Chip-Scale Packaging (WLCSP); providing excellent thermal conductivity, small footprint, and low electrical resistance for wider application usage.
