It handles a 2.7V to 18V input rail and delivers up to 5.3A continuous output with ±8% current-limit accuracy. ## Current-limit accuracy and load budget The ±8% accuracy on the 5.3A current limit means the minimum guaranteed trip point is about 4.9A. When sizing the load, budget for that floor — a 4.5A continuous load leaves roughly 8% headroom before the fuse starts to fold back. The wide 2.7V to 18V input range covers common 3.3V, 5V, and 12V rails without needing a separate pre-regulator. That simplifies the bill of materials on multi-rail boards.","metaTitle":"TPS25942LRVCT Electronic Fuse, 5.3A, 2.7V-18V, Active","metaDescription":"TI TPS25942LRVCT electronic fuse, 5.3A output, 2.7V-18V input, ±8% accuracy, -40°C to 125°C, 20-WQFN.","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 (4x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/931667e7540b17c59e31e61a388aaa66.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS25942LRVCT/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS25942 and TPS25940?","answer":"The TPS25942 and TPS25940 are both electronic fuses in the same family. The key parametric difference is the current-limit accuracy — the TPS25942LRVCT lists ±8% accuracy, while the TPS25940 variant typically targets a different accuracy tier. Confirm the exact accuracy spec for the TPS25940 from its datasheet before substituting."},{"question":"Does TPS25942LRVCT have reverse polarity protection?","answer":"The evidence does not list reverse polarity protection as a feature. The part is an electronic fuse for overcurrent and overvoltage protection on the input rail. For reverse-polarity scenarios, an external protection diode or a dedicated reverse-polarity protection IC should be added upstream."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS25942LRVCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS25942LRVCT when reusing this data.
