It delivers up to 1.7A continuous output with a ±2% current-limit accuracy, which means you can set the trip threshold tight against the load's maximum draw without leaving a big guard band. Surface-mount assembly on an 8-SOIC with standard lead-free reflow profile — no special bake-out or moisture sensitivity level beyond typical MSL-1 or MSL-2 handling.","metaTitle":"TPS25921ADR Electronic Fuse, 4.5V-18V Input, 1.7A Output","metaDescription":"TI TPS25921ADR electronic fuse in 8-SOIC. 4.5V to 18V input range, 1.7A continuous output, ±2% 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":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Accuracy":"±2%","Function":"Electronic Fuse","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","Sensing Method":"-","Voltage - Input":"4.5V ~ 18V","lifecycle_stage":"eol_hot","Current - Output":"1.7A","Base Product Number":"TPS25921","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"8-SOIC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2475b6d32461f459e5de6989c1d3a83b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS25921ADR/alternatives.json"},"ai":{"faq":[{"question":"What is the current limit of TPS25921ADR?","answer":"Continuous output current is rated at 1.7A with a ±2% accuracy on the current-limit threshold."},{"question":"What is the difference between TPS25921ADR and TPS25921AD?","answer":"The TPS25921ADR and TPS25921AD share the same base product number (TPS25921) and electrical specs; the 'R' suffix typically denotes Tape & Reel packaging vs tube or alternate reel format.
