1.2A USB Power Loading Switch
General Description
The LPW5208 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 (16μA) and small package (SOT23-5) is particularly suitable in battery-powered portable equipment.
Features
160mΩ Low RDS(ON), High-side N-MOSFET Guaranteed 1200mA Continuous Current 2.5V to 6V Input Voltage Low Quiescent Current:16μA Soft Start Function Built-In Short-Circuit Protection Built-In Thermal Protection RoHS Compliant and 100% Lead(Pb)-Free
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 c...
