FIXED CURRENT LIMIT POWER
DISTRIBUTION SWITCH
CMOS IC
DESCRIPTION
UTC US2005 is a lo w voltage cost-effective high-side power switch
with curr ent li miting fu nction. It is partic ularly s uitable for ge neral
purpose p ower distributi on and co ntrol i n digita l telev isions (DT V),
printers, set top boxes (STB), PCs, PDAs, and other peripheral devices.
UTC US2005 contains a ch arge pump circuitry to dr ive the internal
MOSFET switch and also incorporate such protection circuits: soft-start
circuit protect these dev ices from being d amaged b y li miting inr ush
current d uring plug- in; ther mal shutd own circuit is us ed to preve nt
catastrophic s witch fai lure fr om hi gh-current loa ds. UVL O is used to
ensure that the device rem ains off unl ess there is a vali d input volta ge
present. A flag output is designed to indicate fault conditions to the local
USB contro ller. Lo wer quiescent curre nt a s 80 μA making this devic e
ideal for portable battery-operated equipment.
UTC US2005 allo ws mom entary high c urrent surg es to pass
unrestricted without sacrifici ng over all s ystem safet y. It also a llows
output slew rate limiting by an external capacitor.
FEATURES
* Built-in 80mΩ N-MOSFET
* Open-drain fault flag output to Indicate fault conditions
* Input voltage varies from 2.5V to 5.5V
* 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)
