FPF1039

Low On-Resistance, Slew-Rate-Controlled Load Switch

Features

Description

1.2 V to 5.5 V Input Voltage Operating Range

Typical R_ON

The FPF1039 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 FPF1039 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.



20 mΩ at V_IN=5.5 V

21 mΩ at V_IN=4.5 V

37 mΩ at V_IN=1.8 V

75 mΩ at V_IN=1.2 V

Slew Rate / Inrush Control with t_R: 2.7 ms (Typical)

3 A Maximum Continuous Current Capability

Output Capacitor Discharge Function

This device has 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.

Low <1 µA Shutdown Current

ESD Protected: Above 8 kV HBM, 1.5 kV CDM

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

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.

Applications

HDD, Storage, and Solid-State Memory Devices

Portable Media Devices, UMPC, Tablets, MIDs

Wireless LAN Cards and Modules

SLR Digital Cameras

Portable Medical Devices

GPS and Navigation Equipment

Industrial Handheld and Enterprise Equipment
