It sits as a secondary protector — not a full fuel gauge or monitor — so the BOM still needs a primary controller for balancing, current sensing, and communication. The single-function over-voltage trigger simplifies qualification if your pack design already carries a primary monitor and just needs a hardware backup for cell over-voltage. ## Cell count and fault coverage The 2 ~ 4 cell range covers the most common Li-ion stack sizes for power tools, portable electronics, and light EV packs. Because fault protection is limited to over-voltage, the device does not guard against under-voltage, over-current, or short-circuit — those must be handled by the primary analog front-end or discrete comparator network. If the pack requires full fault coverage in a single IC, look at a battery monitor like the BQ79612PAPRQ1 which adds over-temperature protection and SPI/UART communication. ## Package and board fit The 8-WSON (2x2) footprint fits space-constrained battery packs. The exposed pad must be soldered to a thermal land on the PCB to meet the -40°C to 110°C operating range. ## Lifecycle and sourcing position Marked Active with ROHS3 compliance, this part carries no end-of-life risk for current production. No LTB window to track.","metaTitle":"BQ294700DSGR Battery Protection IC, 2~4 Cell Li-Ion, 8-WSON","metaDescription":"TI BQ294700DSGR battery protection IC for 2-4 cell Li-Ion packs.
