Its continuous output current rating of 1.7 A sets the load budget — the designer sizes the PCB trace and the load to stay under this ceiling with derating for ambient temperature. The input voltage range spans 4.5 V to 18 V, covering common 5 V, 12 V, and 15 V supply rails without an external regulator. The ±2% current-limit accuracy means the threshold is tight enough to set the limit just above the normal load without wasting headroom on guardband. Surface-mount assembly with the SOIC-8 package uses a standard reflow profile.","metaTitle":"TPS25921LDR Electronic Fuse, 1.7 A, 4.5-18 V, 8-SOIC","metaDescription":"Texas Instruments TPS25921LDR electronic fuse, 1.7 A continuous output, 4.5 V to 18 V input range, ±2% accuracy, -40°C to 125°C junction temp.","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/b00b4c283a534ca7210f42a66ba99d18.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS25921LDR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest alternative to TPS25921LDR?","answer":"The base product number TPS25921 covers multiple current-rating variants in the same family; check the TPS25921 series for higher or lower current options if the 1.7 A rating does not fit the load budget."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS25921LDR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS25921LDR when reusing this data.
