It handles a continuous output current of 5.3 A across an input range of 2.7 V to 18 V, covering common 3.3 V, 5 V, 12 V, and 15 V supply rails without external pre-regulation. The ±8% current-limit accuracy sets the guard-band needed to avoid nuisance trips at the minimum load — a ±8% window means a 5.0 A limit can trip as low as 4.6 A or as high as 5.4 A, so the downstream load must stay below the lower bound. ## Junction temperature and the exposed-pad thermal path Without a proper thermal land, the 5.3 A continuous rating derates significantly above 85°C ambient.","metaTitle":"TPS25942ARVCR Electronic Fuse, 5.3A, 2.7V–18V, Active","metaDescription":"TI TPS25942ARVCR electronic fuse, 5.3A continuous output, 2.7V–18V input range, ±8% accuracy, 20-WQFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Accuracy":"±8%","Function":"Electronic Fuse","Mounting Type":"Surface Mount","Package / Case":"20-WFQFN Exposed Pad","Product Status":"Active","Sensing Method":"-","Voltage - Input":"2.7V ~ 18V","lifecycle_stage":"eol_hot","Current - Output":"5.3A","Base Product Number":"TPS25942","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"20-WQFN (3x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/931667e7540b17c59e31e61a388aaa66.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS25942ARVCR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS25942ARVCR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS25942ARVCR when reusing this data.
