Description
The XA9011 is an integrated 200m power
switch for self-powered and bus-powered
Universal Series Bus (USB) applications. A
built-in charge pump is used to drive the
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
supply current (50µA) 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 condition.
