Supplied in an 8-WFDFN with exposed pad (8-WSON, 2x2 mm), the package requires a thermal land pattern on the PCB to conduct heat from the die to the board plane. Surface-mount assembly with Tape & Reel packaging supports standard pick-and-place and reflow profiles. The small 2x2 mm footprint fits space-constrained battery management circuits on a single-layer or multi-layer board. The base product number BQ24381 identifies the family; the DSGRG4 suffix denotes the 8-WSON package and Tape & Reel quantity. RoHS compliance is standard for this TI catalog line.","metaTitle":"BQ24381DSGRG4 Battery Protection IC, 8-WSON, Active","metaDescription":"Texas Instruments BQ24381DSGRG4 Li-Ion battery protection IC with overcurrent, over/under-voltage, short-circuit, and over-temperature protection.","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)","Function":"Battery Protection","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"8-WFDFN Exposed Pad","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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9e3a9672a431330dc651e3139c56b0e5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24381DSGRG4/alternatives.json"},"ai":{"faq":[{"question":"What faults does the BQ24381DSGRG4 protect against?","answer":"The device provides protection against overcurrent, over-temperature, overvoltage, undervoltage, and short-circuit conditions for single-cell lithium-ion battery packs."},{"question":"What package does the BQ24381DSGRG4 use?","answer":"It is supplied in an 8-WFDFN with exposed pad, also designated as 8-WSON (2x2 mm).
