Single-cell support is the hard constraint — this gauge is built for one Li-ion series cell only. The I²C interface keeps the host-side wiring simple: two lines for clock and data, plus the interrupt line if you use it. Over-temperature fault protection is built in, so the gauge can flag a thermal runaway condition without waiting for the host to poll.
No. The BQ27500DRZT-V130 is specified for a single Li-ion cell only. For a 2-cell pack you would need a different gauge, such as the BQ2084DBT-V143 which supports 2 to 4 cells.
For single-cell automotive applications, the BQ79612PAPRQ1 is a functional alternative with SPI/UART interface and AEC-Q100 qualification, but it is a different grade and package. For multi-cell packs (2-4 cells), the BQ2084DBT-V143 uses an SMBus interface and supports Li-ion/Polymer chemistry. Neither is a drop-in replacement — verify pinout and firmware compatibility before substituting.
