Its primary function is over-voltage fault protection — it monitors each cell voltage and triggers a shutdown when any cell exceeds the over-voltage threshold, preventing cell damage or thermal runaway. Housed in an 8-WFDFN exposed pad package (supplier device package 8-WSON 2x2 mm), it is a surface-mount component suited for compact battery management system (BMS) PCBs where board space is tight. ## Active production — no LTB window to track For a procurement desk, this means no urgency to stockpile or scramble for end-of-life inventory. The part can be specified into new designs without worrying about an imminent EOL notice. ## Over-voltage protection — what the fault trigger means on the bench The BQ294704DSGT monitors each series cell in a 2-to-4-cell Li-Ion stack. When any cell voltage exceeds the factory-set over-voltage threshold, the IC asserts a fault output that can drive an external FET to disconnect the pack from the charger or load. This is the primary protection mechanism against over-charge, which is the dominant failure mode in Li-Ion packs. The 110°C upper limit is above typical Li-Ion cell operating temperatures (usually 60-85°C), so the IC itself is not the thermal bottleneck in the BMS design. The 8-WFDFN exposed pad package (8-WSON, 2x2 mm body) requires a thermal pad on the PCB for adequate heat dissipation. The exposed pad is typically connected to the ground plane. The 0.5 mm pitch is fine-pitch but hand-solderable with a hot-air rework station — the pad geometry is standard for this package class.","metaTitle":"Texas Instruments BQ294704DSGT Battery Protection IC","metaDescription":"Texas Instruments BQ294704DSGT battery protection IC for 2-4 cell Li-Ion packs, over-voltage fault protection, 8-WSON 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-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":"$1.01","priceTiers":[{"qty":1,"price":"$1.01000","currency":"USD"},{"qty":10,"price":"$0.90700","currency":"USD"},{"qty":25,"price":"$0.86080","currency":"USD"},{"qty":100,"price":"$0.70700","currency":"USD"},{"qty":250,"price":"$0.66092","currency":"USD"},{"qty":500,"price":"$0.58406","currency":"USD"},{"qty":1250,"price":"$0.46110","currency":"USD"},{"qty":2500,"price":"$0.43500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/cfe71c12a864ca4f7a52b641520fdc73.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ294704DSGT/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional alternative to BQ294704DSGT — BQ296217DSGT?","answer":"The BQ296217DSGT is a peer device with the same function (battery protection), same cell count range (2 to 4 cells), same fault protection type (over-voltage), same battery chemistry (Lithium-Ion), and the same operating temperature range (-40°C to 110°C). The primary difference is the package — both are 8-WFDFN exposed pad, but the BQ296217 may have a different factory-set over-voltage threshold. Confirm the threshold value against your BMS design before substituting. The BQ294704DSGT remains the primary recommended part for new designs."},{"question":"What compliance documentation does Texas Instruments provide for BQ294704DSGT?","answer":"Texas Instruments certifies the BQ294704DSGT as ROHS3 compliant. Standard documentation includes the datasheet, application notes for battery protection circuit design, and a product brief. No UL, IEC, or REACH-specific certification is listed in the product record, but TI typically provides REACH and conflict minerals declarations on request through their compliance portal."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ294704DSGT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ294704DSGT when reusing this data.
