1 / 4 page  LPW5201-00 Nov.-2017 Email: marketing@lowpowersemi.com www.lowpowersemi.com Page 1 of 4 Preliminary Datasheet LPW5201 Power Switch with Programmable Current Limit General Description The LPW5201 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. Several protection functions include soft start to limit inrush current during plug-in, current limiting at 600mA, 1100mA or 2100mA to meet USB power requirement, and thermal shutdown to protect damage under over current conditions.
