Its fault-protection set covers over-current, over-temperature, and over/under-voltage conditions — the three failure modes that dominate Li-ion safety incidents. Operating temperature spans 0°C to 125°C (junction), which covers the industrial ambient range inside a portable device enclosure but does not extend to the -40°C cold-crank floor of automotive-grade parts. Housed in a 12-VFDFN exposed-pad package (supplier device package 12-VSON, 4×3 mm), the IC requires a thermal-land pattern on the PCB to sink heat from the protection FETs during sustained over-current events. Cut Tape works for prototype or low-volume builds. Texas Instruments has marked the BQ24314DSJR as Obsolete. Available through independent distribution — quantities are lot-specific, and pricing is confirmed at RFQ. The base product number BQ24314 identifies the family; a pin-compatible alternative in the same family may exist, but no cross-reference is documented here.","metaTitle":"BQ24314DSJR Battery Protection IC, Obsolete","metaDescription":"Texas Instruments BQ24314DSJR Li-ion battery protection IC with over-current, over-temperature, over/under-voltage fault protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Battery Protection","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"12-VFDFN Exposed Pad","Product Status":"Obsolete","Number of Cells":"-","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over/Under Voltage","Battery Chemistry":"Lithium Ion","Base Product Number":"BQ24314","Operating Temperature":"0°C~125°C(TJ)","Supplier Device Package":"12-VSON (4x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/333c2e0185e5e7fb86c37428c311a764.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24314DSJR/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the BQ24314DSJR and get a price?","answer":"Sourced through independent distribution against an RFQ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24314DSJR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24314DSJR when reusing this data.
