The BQ27411DRZT-G1C is a single-cell Li-Ion battery monitor from Texas Instruments' Impedance Track™ series. It uses the patented Impedance Track™ algorithm to report state-of-charge, voltage, current, and temperature over an I²C interface.
Communication with the host processor runs over a standard I²C bus, keeping the wiring to two lines — SDA and SCL.
The datasheet is available from Texas Instruments under the base product number BQ27411. It covers the full register map, Impedance Track™ algorithm configuration, and PCB layout guidelines for the 12-SON package.
No. This part is specified for a single cell. For multi-cell packs, consider the BQ2084DBT-V143 which supports 2 to 4 cells.
