ELPW5210 1.5A Power Switch with Programmable Current Limit

General Description

The ELPW5210 is an integrated 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  (16μA) and small  package (SOT23-5) is particularly suitable in battery-powered

portable equipment.

Several protection functions include soft start to limit inrush current during plug-in, current limiting at 1500mA  to   meet USB power requirement,and thermal shutdown  to protect damage under over current conditions.
