微源半导体 LPW5210 SOT23-5 1.5A可编程限流电源开关

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 (30μA) and small package (SOT23-5) is particularly suitable in battery-powered portable equipment.

LPW5210 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.
