Its primary job is over-voltage fault protection — it monitors each cell voltage and triggers an external discharge FET when any cell exceeds the over-voltage threshold. This is a single-function protector, not a full fuel-gauge or monitor; there is no overcurrent or short-circuit detection on-chip. The 8-TSSOP package keeps the board footprint small, and the -40°C to 110°C operating range suits both portable equipment and industrial battery enclosures. ## Over-voltage only — what that means for your BOM The 2-4 cell range covers common Li-ion pack voltages. The over-voltage threshold is factory-set; there is no external resistor programming. If your application also needs overcurrent, look at a multi-function protector like the BQ297xx series. ## Active production, no end-of-life pressure The BQ29412PWR is listed as Active with ROHS3 compliance. For volume production or spares, this part is sourced through independent distribution and quoted to order against an RFQ.","metaTitle":"BQ29412PWR Battery Protection IC, 2-4 Cell Li-Ion, 8-TSSOP","metaDescription":"TI BQ29412PWR battery protection IC for 2-4 cell Li-ion packs.

The BQ29412PWR is set for a higher threshold (typically 4.35 V per cell), while the BQ29410PWR triggers at a lower voltage (typically 4.2 V per cell).
