The BQ27541DRZT-V200 is a Texas Instruments Impedance Track™ fuel gauge designed for single-cell Lithium Ion battery packs. It communicates with the host system over an I²C interface, reporting remaining capacity, state-of-charge, and voltage with the algorithm's characteristic accuracy across the cell's age and temperature.
No. The BQ27541DRZT-V200 is designed for a single series cell. Using it on a 2-cell pack would produce inaccurate state-of-charge readings and may violate the gauge's input voltage limits. For multi-cell packs, consider the BQ2084DBT-V143 (2 to 4 cells, SMBus interface) or the BQ79612PAPRQ1 (automotive-grade, 1-cell with SPI/UART).
