General Description
The LPW5210 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.
