Its primary function is over-voltage fault protection, a critical safety feature that prevents cell damage during charging by monitoring each cell's voltage and disconnecting the pack if any cell exceeds a safe threshold. This device is typically deployed in battery management systems (BMS) for power tools, portable electronics, e-bikes, and backup power units where reliable cell-level protection is required. ## Package and Mounting for Space-Constrained Designs Housed in an 8-WSON (2x2 mm) package, the BQ294700DSGT is a surface-mount device suited for compact PCB layouts. The exposed pad provides a low thermal resistance path to the board. ## Temperature Grade and Operating Environment Rated for an operating temperature range of -40°C to 110°C (TA), this IC covers industrial and extended-commercial environments. It can be used in outdoor telecom gear, automotive cabin modules, and industrial battery packs that experience wide thermal swings without performance degradation.","metaTitle":"BQ294700DSGT Battery Protection IC, 2-4 Cell Li-Ion, 8-WSON","metaDescription":"TI BQ294700DSGT battery protection IC for 2-4 cell Li-Ion packs, over-voltage protection, -40°C to 110°C, 8-WSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"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","stockQuantity":0,"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},"ai":{"faq":[{"question":"What are equivalent or alternative parts to BQ294700DSGT?","answer":"A functional alternative within the same family is the BQ79612PAPRQ1, which is an automotive-grade (AEC-Q100) battery monitor with SPI/UART interface and over-temperature protection, but it supports only 1 cell and targets functional safety applications. For a 2-4 cell monitor with SMBus interface, the BQ2084DBT-V143 is an alternative, though it has a narrower temperature range of -20°C to 85°C and comes in a tube package. Neither is a direct pin-compatible replacement; verify your system requirements before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ294700DSGT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ294700DSGT when reusing this data.
