LPW5220 - 3.0A Power Switch

Datasheet Summary

Description

The LPW5220 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.

Features

  • 110mΩ Low RDS(ON), High-side N-MOSFET.
  • Guaranteed 3000mA Continuous Current.
  • 2.5V to 6V Input Voltage.
  • Low Quiescent Current:36μA.
  • Soft Start Function.
  • Built-In Short-Circuit Protect.

Preliminary Datasheet LPW5220 3.0A Power Switch with Programmable Current Limit General Description The LPW5220 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 (36μA) and small package (ESOP-8) is particularly suitable in battery-powered portable equipment. Several protection functions include soft start to limit inrush current during plug-in, current limiting at 3000mA to meet USB power requirement, and thermal shutdown to protect damage under over current conditions.
