LPW5202
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.
