It operates from a 2.7V to 18V input rail and delivers up to 4A continuous output, making it a fit for 5V, 12V, and intermediate bus architectures in industrial and automotive environments. ## Current-limit accuracy and trip margin The eFuse's current-limit accuracy is ±7.5%, which means the actual trip threshold can vary by that amount from the programmed value. For a 4A design, the minimum guaranteed trip point is 3.7A, so the load budget must stay below that to avoid nuisance trips. This tolerance is typical for integrated eFuses and should be factored into the overcurrent protection margin during BOM sizing. ROHS3 compliant. For new designs or ongoing production, there is no imminent end-of-life concern. ## Package and mounting checklist The device is supplied in an 8-WFDFN exposed pad package (8-WSON, 2x2 mm). Surface-mount only. Tape & Reel and Cut Tape options are available for prototype or production volumes.","metaTitle":"TPS259533DSGT eFuse 2.7V-18V 4A 8-WSON – Texas Instruments","metaDescription":"Active eFuse, 2.7V-18V input, 4A output, ±7.5% accuracy, -40°C to 125°C, 8-WSON (2x2) package.
