TI Impedance Track battery fuel gauge for handheld electronics

Texas Instruments (TI) has introduced single-cell battery fuel gauge ICs with Impedance Track technology, which is half the size of its predecessor.

The tiny bq27505 stand-alone lithium battery capacity monitoring and reporting device resides in the system and measures only 2.5mm x 2mm x 0.625mm, and supports portable applications.

Impedance Track technology predicts battery capacity under all operating conditions, including battery age, temperature and discharge behavior, the company said.
