It delivers up to 4A continuous output with a ±7.5% accuracy on the current-limit threshold, so the designer can set the trip point within a tight window without oversizing the protection. Housed in an 8-WFDFN with exposed pad (also listed as 8-WSON 2x2 mm), the part is surface-mount and suited for compact PCB layouts.","metaTitle":"TPS259570DSGR Electronic Fuse, 2.7V-18V, 4A, Active","metaDescription":"Texas Instruments TPS259570DSGR electronic fuse in 8-WFDFN package. 4A output, ±7.5% accuracy, -40°C to 125°C.
