US202

Preliminary

CMOS IC

100mΩ POWER DISTRIBUTION

SWITCHES

DESCRIPTION

The US202 is a power distribution switch. It is particularly suitable

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

applications. It has 23μA 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 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 can be used in such applications such as

battery-powered equipments, motherboard USB power switchs, USB

device power switchs, hot-plug power supplies, battery-charger

circuits and so on.
