For a 12V automotive ECU drawing 4A nominal, this leaves roughly 25% headroom before the limit threshold is reached. The ±8% current-limit accuracy means a programmed 5A limit could trip as low as 4.6A or as high as 5.4A. Design the load budget to stay below the lower bound to avoid nuisance trips at temperature extremes. For dual-sourcing, evaluate the broader TPS25940 family for variants with similar current and accuracy specs. ## Package and footprint — 20-WQFN with exposed pad Surface-mount assembly only — the WQFN package requires a solder-paste stencil and reflow profile. The exposed pad is electrically connected to the die substrate (typically GND), so the PCB pad should be tied to the ground plane.","metaTitle":"TPS25940LQRVCRQ1 Texas Instruments eFuse, 2.7V-18V, 5.3A","metaDescription":"Texas Instruments TPS25940LQRVCRQ1 automotive eFuse, AEC-Q100 qualified. 2.7V to 18V input, 5.3A output, ±8% accuracy, -40°C to 125°C.","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","Supplier Device Package":"20-WQFN (4x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6da93b55599ff9bf26ad649f3590fc52.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS25940LQRVCRQ1/alternatives.json"},"ai":{"faq":[{"question":"What is the output current limit of TPS25940LQRVCRQ1?","answer":"The TPS25940LQRVCRQ1 is rated for a continuous output current of 5.3A.
