It is designed for single-cell lithium-ion battery packs in portable equipment where a compact, integrated protection solution is needed. ## Fault protection set — what it catches The device integrates four protection functions: overcurrent, over-temperature, over/under voltage, and short-circuit. This means a single chip replaces discrete comparators and sense resistors for the battery cell monitoring, shrinking the BOM and board area on a battery management PCB. ## Temperature grade and reflow reality The 8-WSON (2x2 mm) exposed-pad package demands a solder stencil aperture covering at least 50% of the pad area for thermal transfer; check the MSL rating before the reflow profile is locked. ## Lifecycle and sourcing posture No official second source or pin-compatible alternate is documented in the TI cross-reference database, so the BOM should treat this as a sole-source line item.","metaTitle":"BQ24351DSGR Battery Protection IC","metaDescription":"TI BQ24351DSGR Li-Ion battery protection IC with overcurrent, over/under voltage, short circuit, and overtemperature protection. -40°C to +85°C, 8-WSON package.","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","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":"BQ24351","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"8-WSON (2x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5550","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a331b30115577de592d16494059a3567.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is BQ24351DSGR used for?","answer":"It is a Li-Ion battery protection IC that guards against overcurrent, over-temperature, over/under voltage, and short-circuit faults in single-cell lithium-ion battery packs."},{"question":"Does BQ24351DSGR have overcurrent protection?","answer":"Yes, overcurrent protection is one of the four integrated fault protections, alongside over-temperature, over/under voltage, and short-circuit."},{"question":"What is the difference between BQ24351DSGR and BQ24350DSGR?","answer":"The BQ24350DSGR is a sibling in the same protection family; the key difference is typically the overvoltage threshold setpoint or enable logic.
