US202 Datasheet
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.
