"USB电源转换器
The XZ1101 is an integrated 100mΩ 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 NMOSFET 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 (23μA) 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 1.** to meet USB power requirement, and thermal shutdown to protect damage under over current conditions."
