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

General Description

The RT9702 and RT9702A are 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

voltage drop requirements; and a flag output is available

to indicate fault conditions to the local USB controller.

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 800mA for 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.

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

packages requiring minimum board space and smallest

components.
