Its single job is overvoltage fault protection — it monitors each cell and triggers an output when any cell exceeds the overvoltage threshold. There is no undervoltage or overcurrent detection on this device; the BQ296212DSGT is a secondary protector designed to back up the primary fuel gauge or charger IC. The part lives in an 8-WSON (2x2 mm) package, small enough for tight battery-pack layouts. Operating temperature spans -40°C to 110°C, so it handles the warm interior of a sealed pack during charge and discharge cycles, but not the under-hood extremes of an automotive traction battery. ## What the ratings mean for your BOM The 2-4 cell range is the first fit check: this part works with 2S, 3S, or 4S Li-ion packs. If your design uses a 1S or 5S+ stack, this is not the part. The overvoltage-only protection means you still need a primary protector or fuel gauge that handles undervoltage, overcurrent, and short-circuit — the BQ296212DSGT is a second layer of safety, not the sole protector. The -40°C to 110°C temperature grade covers most portable and industrial battery applications. For a pack that sees sustained 110°C internal temperature, verify the derating on the overvoltage threshold — the datasheet's electrical characteristics table shows the threshold drift over temperature. ## Lifecycle and sourcing The BQ296212DSGT is listed as Active with ROHS3 compliance.","metaTitle":"TI BQ296212DSGT Battery Protection IC, 2-4 Cell Li-ion","metaDescription":"TI BQ296212DSGT Li-ion battery protection IC for 2-4 cells, overvoltage fault protection, -40°C to 110°C, 8-WSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Battery Protection","Mounting Type":"Surface Mount","Package / Case":"8-WFDFN Exposed Pad","Number of Cells":"2 ~ 4","lifecycle_stage":"eol_hot","Fault Protection":"Over Voltage","Battery Chemistry":"Lithium Ion","Operating Temperature":"-40°C ~ 110°C (TA)","Supplier Device Package":"8-WSON (2x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.16","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.16000","currency":"USD"},{"qty":10,"price":"$1.03800","currency":"USD"},{"qty":25,"price":"$0.98520","currency":"USD"},{"qty":100,"price":"$0.80940","currency":"USD"},{"qty":250,"price":"$0.75664","currency":"USD"},{"qty":500,"price":"$0.66864","currency":"USD"},{"qty":1250,"price":"$0.52788","currency":"USD"},{"qty":2500,"price":"$0.49800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/aa031d342c6ffc05809cd2a97eabe764.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ296212DSGT compatible with 4-cell Li-ion?","answer":"Yes, the BQ296212DSGT supports 2 to 4 series cells, including 4S Li-ion packs."},{"question":"What is the difference between BQ296212DSGT and BQ296212DSGR?","answer":"The BQ296212DSGT and BQ296212DSGR are the same device; the suffix difference indicates the reel packaging option.
