RT9706

80mΩ, 500mA High-Side Power Switch with Flag

General Description

Features

^zCompliant to USB Specifications

The RT9706 is a cost-effective, low voltage, single

N-Channel MOSFET high-side power switch, optimized

for self-powered and bus-powered Universal Serial Bus

(USB) applications. The RT9706 equipped with a charge

pump circuitry to drive the internal MOSFET switch; the

switch's low R_DS(ON)80mΩ, meets USB voltage drop

requirements; and a flag output is available to indicate

fault conditions to the local USB controller.

^zBuilt-In (Typically 80mΩ) N-Channel MOSFET

^zOutput Can Be Forced Higher than Input (Off-State)

^zLow Supply Current :

`25μA Typical at Switch On State

`0.1μA Typical at Switch Off State

^zGuaranteed 500mA Continuous Load Current

^zWide Input Voltage Ranges : 2V to 5.5V

^zOpen-Drain Fault Flag Output

Additional features include soft-start to limit inrush current

during plug-in, thermal shutdown to prevent catastrophic

switch failure from high-current loads, under-voltage

lockout (UVLO) to ensure that the device remains off

unless there is a valid input voltage present, lower

quiescent current as 25μA making this device ideal for

portable battery operated equipment.

^zHot Plug-In Application (Soft-Start)

^z1.7V Typical Under-Voltage Lockout (UVLO)

^zCurrent Limiting Protection

z Thermal Shutdown Protection

z Reverse Current Flow Blocking (no body diode)

z Smallest SOT-23-5 Package Minimizes Board Space

z UL Approved−E219878

The RT9706 is available in SOT-23-5 package requiring

minimum board space and smallest components.

z RoHS Compliant and 100% Lead (Pb)-Free

Applications

z USB Bus/Self Powered Hubs
