RT9711

80mΩ, 1.5A High-Side Power Switches with Flag

General Description

Features

^zCompliant to USB Specifications

The RT9711 is a low voltage, singleN-MOSFET high-side

power switch, optimized for self-powered and bus- powered

Universal Serial Bus (USB) applications. The RT9711

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 N-MOSFET

` Typical R_DS(ON): 80mΩ (SOT-23-5), 90mΩ (SOP-8)

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

^zLow Supply Current :

25μA Typical at Switch On State

1μA Typical at Switch Off State

^zGuaranteed 1.5A Continuous Load Current

^zWide Input Voltage Ranges : 2.5V 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. The maximum

current is limited to typically 2.5A in dual ports in

accordance with the USB power requirements, 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)

z Current Limiting Protection

z Thermal Shutdown Protection

z Reverse Current Flow Blocking (no body diode)

z UL Approved−E219878

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

The RT9711 is available in SOT-23-5 and SOP-8 packages

requiring minimum board space and smallest components.
