When any cell exceeds the over-voltage threshold, the IC triggers a fault output that can drive an external FET to disconnect the pack — the protection logic is hardwired, no firmware needed. Operating from -40°C to 110°C, it covers the full commercial and industrial temperature envelope for portable and backup-power applications. ## SM8 package — rework and layout notes Housed in an 8-lead LSSOP/MSOP with 0.110-inch body width (2.80 mm), the SM8 package is a low-profile, fine-pitch SOIC variant suited for space-constrained battery packs. Pin 1 is clearly marked on the top-side silkscreen; the narrow 2.80 mm width means the footprint fits on a single-layer PCB if the traces are kept to 0.25 mm or finer.","metaTitle":"BQ29412DCTT Texas Instruments Battery Protection IC","metaDescription":"Texas Instruments BQ29412DCTT Li-Ion battery protection IC for 2-4 cells, over-voltage fault protection, -40 to 110°C, SM8 package, active production, ROHS3.","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-LSSOP, 8-MSOP (0.110\\\", 2.80mm Width)","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":"SM8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.99","priceTiers":[{"qty":1,"price":"$2.99000","currency":"USD"},{"qty":10,"price":"$2.68700","currency":"USD"},{"qty":25,"price":"$2.54000","currency":"USD"},{"qty":100,"price":"$2.20140","currency":"USD"},{"qty":250,"price":"$2.08848","currency":"USD"},{"qty":500,"price":"$1.87398","currency":"USD"},{"qty":1250,"price":"$1.59750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/96073a6de0d67c039c189c59672bf30d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ29412DCTT/alternatives.json"},"ai":{"faq":[{"question":"What is BQ29412DCTT's function and what battery chemistry does it support?","answer":"It is a battery protection IC with over-voltage fault detection, designed specifically for Lithium-Ion (Li-Ion) battery packs.
