The Texas Instruments BQ28Z610DRZR-R1 is an active battery fuel gauge IC with an integrated protector, suitable for 1 to 2 series Li-Ion/Li-Polymer battery packs. It utilizes the Impedance Track™ algorithm for accurate state-of-charge monitoring and includes SHA-1 authentication for enhanced battery pack security.
Key electrical features include an I2C communication interface operating at 400 kHz, a high-accuracy coulomb counter with low input offset error, and support for small current sense resistors down to 1 mΩ, enabling measurements as low as 1 mA. The device also supports programmable protection levels for voltage, current, and temperature, along with cell balancing capabilities.
Packaged in a compact 12-pin VSON (DRZ) with exposed pad, the BQ28Z610DRZR-R1 is designed for surface mount applications. Its operating temperature range is -40°C to 85°C, making it suitable for a wide variety of environments. The IC provides autonomous battery charging control and enables serial bus communication during fault conditions via a high-side N-CH FET drive.
