FIXED CURRENT LIMIT POWER

DISTRIBUTION SWITCH



DESCRIPTION

UTC US2005 is a low voltage cost-effective high-side power switch

with current limiting function. It is particularly suitable for general

purpose power distribution and control in digital televisions (DTV),

printers, set top boxes (STB), PCs, PDAs, and other peripheral devices.

UTC US2005 contains a charge pump circuitry to drive the internal

MOSFET switch and also incorporate such protection circuits: soft-start

circuit protect these devices from being damaged by limiting inrush

current during plug-in; thermal shutdown circuit is used to prevent

catastrophic switch failure from high-current loads. UVLO is used to

ensure that the device remains off unless there is a valid input voltage

present. A flag output is designed to indicate fault conditions to the local

USB controller. Lower quiescent current as 80μA making this device

ideal for portable battery-operated equipment.

UTC US2005 allows momentary high current surges to pass

unrestricted without sacrificing overall system safety. It also allows

output slew rate limiting by an external capacitor.



FEATURES

* Built-in 80mΩ N-MOSFET

* 80μA low quiescent current

* Current limit values of 0.5A, 0.8A, and 1.2A

* Automatic-on output after fault

* Thermal protection

* Under voltage lock-out (UVLO)
