5.3 A eFuse for 2.7 V to 18 V power rails
The Texas Instruments TPS25940ARVCR is an electronic fuse (eFuse) that integrates the power switch, current sensing, and protection logic into a single 20-WFQFN package with exposed pad.
The ±8% accuracy on the current-limit threshold means the designer can set the trip point closer to the nominal load without oversizing the trace width or connector rating for worst-case tolerance. At 5.3 A nominal output, the actual trip point stays between 4.88 A and 5.72 A across temperature and process — tight enough to protect a 6 A-rated downstream connector without nuisance trips on inrush.
