US202/A

CMOS IC

100mΩ POWER DISTRIBUTION

SWITCHES



DESCRIPTION

The US202/A is a power distribution switch. It is particularly

suitable for self-powered and bus-powered USB (Universal Series

bus) applications. It has 28μA low quiescent supply current that

meets the requirements of battery-powered portable equipments.

A built-in charge pump is used to drive the N-channel N-MOSFET

that is free of parasitic body diode to eliminate any reversed current

flow across the switch when it is powered off.

The US202/A incorporates some protection circuits such as

current limit and short protection circuits, soft start circuit, thermal

shutdown and UVLO (Under-voltage Lockout) protection circuits.

The thermal shutdown circuits protect this device from damage when

over current occurs, and the soft start circuits are used to prevent

inrush current when plug-in event occurs.

The US202/A can be used in such applications such as

battery-powered equipments, motherboard USB power switches,

USB device power switches, hot-plug power supplies,

battery-charger circuits and so on.


