eFuse for 2.7V to 18V rails — what the ratings mean
The Texas Instruments TPS25944LRVCT is an electronic fuse (eFuse) in a 20-WFQFN exposed-pad package, designed to protect downstream loads from overcurrent, overvoltage, and inrush events on supply rails from 2.7V to 18V. It delivers a continuous output current of 5.3A with a current-limit accuracy of ±8%, which means the designer can set the threshold closer to the load rating without the guard-band that looser-tolerance parts demand.
