Preliminary Datasheet

LPW5203

3A Smart Power Switch

General Description

The LPW5203 is an integrated power switch for

self-powered and bus-powered Universal Series Bus

applications. A built-in charge pump is used to drive

the N-Channel MOSFET that is free of parasitic body

diode to eliminate any reversed current flow across the

switch when it is powered off. Its low quiescent current

(30μA) and small package (SOT-23-5) is particularly

suitable in battery-powered portable equipment.
