Preliminary

RT9701B

100mΩ Power Distribution Switches

General Description

Features

^z100mΩ Typ. High-Side NMOSFET

^zGuaranteed 1.1A Continuous Current

^z1.5A Current Limit

The RT9701B is an integrated 100mΩ 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

(23μA) and small package (SOT-23-5) is particularly

suitable in battery-powered portable equipment.

^zSmall SOT-23-5 Package Minimizes Board Space

^zSoft Start

^zThermal Protection

^zLow 23μA Supply Current

^zWide Input Voltage Range : 3.5V to 6V

^zUL Approved - #E219878

Several protection functions include soft start to limit

inrush current during plug-in, current limiting at 1.5A to

meet USB power requirement, and thermal shutdown to

protect damage under over current conditions.

^zRoHS Compliant and 100% Lead (Pb)-Free

Applications

z Battery-Powered Equipment

z Motherboard USB Power Switch

z USBDevice Power Switch

z Hot-Plug Power Supplies

z Battery-Charger Circuits
