资 源 简 介

The RT9701B is an integrated 100mΩ power switch forself-powered and bus-powered Universal Series Bus(USB) applicaTIons. A built-in charge pump is used todrive the N-MOSFET that is free of parasiTIc body diode toeliminate any reversed current flow across the switch whenit is powered off. Its low quiescent current (23uA) andsmall package (SOT-23-5) is parTIcularly suitable inbattery-powered portable equipment.Several protecTIon functions include soft start to limit inrushcurrent during plug-in, current limiting at 1.5A to meetUSB power requirement, and thermal shutdown to protectdamage under over current conditions.
