The AEC-Q100 qualification places it in under-hood and chassis-domain power distribution — think ECU input protection, ADAS sensor supply rails, and body controller load switches where a resettable overcurrent protector beats a one-shot fuse. The ±8% accuracy on the current-limit threshold means the designer can set the trip point closer to the load's normal peak current without false trips at temperature. For a 5A nominal load, the trip band sits between 4.6A and 5.4A — tight enough to protect a 5.3A-rated downstream converter without oversizing the eFuse. The supplier device package is 20-WQFN (4x3). Surface-mount only; no through-hole variant. No last-time-buy notice, no end-of-life window.","metaTitle":"TPS25940AQRVCTQ1 Automotive eFuse, 2.7V-18V, 5.3A, AEC-Q100","metaDescription":"Texas Instruments TPS25940AQRVCTQ1 electronic fuse, AEC-Q100 qualified, 2.7V-18V input, 5.3A output, -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":"Automotive, AEC-Q100","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":"TPS25940","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"20-WQFN (4x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6da93b55599ff9bf26ad649f3590fc52.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS25940AQRVCTQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS25940AQRVCTQ1 overcurrent protected?","answer":"Yes, it is an electronic fuse whose primary function is overcurrent protection.
