The BQ27411DRZT-G1A is a dedicated single-cell Li-Ion battery monitor — if your pack has two or more series cells, this part cannot track the stack voltage without external level shifting.
Sourced per RFQ — confirm current lead time and price against your BOM quantity at quote time.
Submit an RFQ for BQ27411DRZT-G1A.
Yes. The part is a single-cell Li-Ion monitor. A 3.7V Li-Po cell is within the Li-Ion chemistry family and the gauge handles the full 2.5V–4.5V typical range of a 1S Li-Po pack.
The BQ27421 is a newer Impedance Track gauge with a different register map and package option. Pin compatibility is not guaranteed — review the BQ27421 datasheet for I²C address and command differences before assuming a drop-in swap.
The BQ79612PAPRQ1 is an automotive-grade (AEC-Q100) single-cell monitor with SPI/UART interface, not a direct I²C replacement. For a non-automotive I²C gauge, the BQ27421 is the more natural cross-shop candidate.
