The continuous output current rating is 5.3 A, which sets the load budget for the protected rail. The ±8% accuracy on the current-limit threshold means the nominal trip point must be set with headroom above the worst-case load current to prevent nuisance tripping — a 5 A continuous load on a 5.3 A limit leaves only 6% margin, so the designer should account for the full ±8% tolerance band. Mounting is surface-mount only, with the exposed pad as the primary heat path. This removes the last-time-buy risk for new designs and production ramps.","metaTitle":"TPS25944LRVCR Electronic Fuse, 5.3 A, 2.7-18 V, 20-WQFN","metaDescription":"TI TPS25944LRVCR electronic fuse, ±8% accuracy, 5.3 A continuous output, 2.7 V to 18 V input range, -40°C to 125°C junction, 20-WQFN 4x3 mm.","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":"TPS25944","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"20-WQFN (4x3)"}},"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/TPS25944LRVCR/alternatives.json"},"ai":{"faq":[{"question":"Can TPS25944LRVCR be used for 5V overcurrent protection?","answer":"Yes.
