The 8-WSON (2x2 mm) exposed-pad package requires the PCB layout engineer to connect the thermal pad to a ground-plane copper area for adequate heat spreading. The 8-WFDFN case code means the pad is on the bottom; a via array under the pad helps pull heat into the inner layers. Sourcing is direct through TI-authorized channels — we can quote against your BOM quantity and confirm current lead time at quote time.","metaTitle":"BQ24381DSGT Battery Protection IC – TI, 8-WSON, Active","metaDescription":"Texas Instruments BQ24381DSGT Li-Ion battery protection IC with over-current, over/under-voltage, short-circuit, and thermal fault protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","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":"8-WFDFN Exposed Pad","Product Status":"Active","Number of Cells":"-","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over/Under Voltage, Short Circuit","Battery Chemistry":"Lithium Ion","Base Product Number":"BQ24381","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"8-WSON (2x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9700","priceTiers":[{"qty":1,"price":"$0.97000","currency":"USD"},{"qty":10,"price":"$0.86600","currency":"USD"},{"qty":25,"price":"$0.82200","currency":"USD"},{"qty":100,"price":"$0.67530","currency":"USD"},{"qty":250,"price":"$0.63128","currency":"USD"},{"qty":500,"price":"$0.55788","currency":"USD"},{"qty":1250,"price":"$0.44043","currency":"USD"},{"qty":2500,"price":"$0.41550","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9e3a9672a431330dc651e3139c56b0e5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24381DSGT/alternatives.json"},"ai":{"faq":[{"question":"What is the BQ24381DSGT used for?","answer":"It is a dedicated Li-Ion battery protection IC. Typical applications include single-cell Li-Ion packs in portable devices, power tools, medical monitors, and industrial instrumentation where the battery must be protected against over-current, over/under-voltage, short-circuit, and over-temperature conditions."},{"question":"Is the BQ79612PAPRQ1 a direct functional replacement for the BQ24381DSGT?","answer":"No. The BQ79612PAPRQ1 is an automotive-grade battery monitor with SPI/UART interface, not a protection IC. The BQ24381DSGT is a standalone protection device with no digital interface. They serve different roles: the BQ79612 monitors cell voltage and reports data; the BQ24381 protects against fault conditions autonomously."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24381DSGT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24381DSGT when reusing this data.
