ELPW5209数据手册E-CMOS中文资料规格书

描述 Description

The ELPW5209 is an integrated 90mΩ power switch for self-powered and bus powered Universal Series Bus(USB) applications. Abuilt-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. It’s low quiescent current(16μA) 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 set to meet power requirement, and thermal shutdown to protect damage under over current conditions.
