BQ27210DRKR

The BQ27210DRKR from Texas Instruments is an active battery fuel gauge IC specifically designed for portable applications utilizing single-cell Lithium-Ion and Lithium-Polymer batteries. This device supports a battery capacity range from 300 mAh to 6000 mAh and features the Impedance Track™ algorithm for accurate battery monitoring.

With an I2C communication interface, the BQ27210DRKR provides accurate reporting of time-to-empty, available capacity compensated for discharge rate, temperature, and age, and end-of-discharge voltage. It also offers automatic capacity reduction with age and reports temperature, voltage, and current. The IC performs high-accuracy charge and discharge current integration with automatic offset calibration.

Packaged in a 10-VSON (3x4) or 10-VFDFN Exposed Pad, this IC is suitable for surface mount applications. It operates within a temperature range of -20°C to 70°C. The device supports multiple low-power operating modes, including Active (< 90 µA), Sleep (< 2.5 µA), Ship (< 2 µA), Hibernate (< 1.5 µA), and Data Retention (< 20 nA), making it ideal for power-sensitive portable devices.

Applications for the BQ27210DRKR include PDAs, smartphones, MP3 players, digital cameras, internet appliances, and other handheld devices requiring precise battery management.
