Power Distribution Switches

General Description

The LPW5202 is an integrated 120mΩ power switch for

self-powered and bus-powered Universal Series Bus

(USB) 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 (19µA) and small package (SOT-23-5) is

particularly

suitable

in

battery-powered

portable

equipment.

Several protection functions include soft start to limit

inrush current during plug-in, current limiting at 1.5A to

meet USB power requirement, and thermal shutdown to

protect damage under over current conditions.
