RT9702/A

80mΩ, 500mA/1.1A High-Side Power Switches with Flag

General Description

Features

^zCompliant to USB Specifications

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

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

^zLow Supply Current :

The RT9702 and RT9702Aare cost-effective, low voltage,

single N-Channel MOSFET high-side power switches,

optimized for self-powered and bus- powered Universal

Serial Bus (USB) applications. The RT9702/A 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.

25μA Typical at Switch On State

1μA Typical at Switch Off State

^zGuaranteed 500mA/RT9702 and 1.1A/RT9702A

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, fault current

is limited to typically 800mAfor RT9702 in single port and

1.5A for RT9702A in dual ports in accordance with the

USB power requirements, lower quiescent current as 25μA

making this device ideal for portable battery-operated

equipment.

z Hot Plug-In Application (Soft-Start)

z 1.7V Typical Under-Voltage Lockout (UVLO)

z Current Limiting Protection

z Thermal Shutdown Protection

z Reverse Current Flow Blocking (no body diode)

z Smallest SOT-23-5 and TSOT-23-5 Packages

Minimizes Board Space

z UL Approved−E219878

z TUV IEC60950-1 : 2005 Certified

The RT9702/A is available in SOT-23-5 and TSOT-23-5

packages requiring minimum board space and smallest

components.

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

Applications

z USB Bus/Self Powered Hubs
