Overview
UNISONIC TECHNOLOGIES CO.
, LTD US2005 Preliminary CMOS IC FIXED CURRENT LIMIT POWER DISTRIBUTION SWITCH  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.
