Battery fuel gauges with Impedance Track™ technology

Single-cell and multi-cell battery fuel gauges from Texas Instruments accurately predict battery run time. Featuring TI’s patented Impedance Track technology, the IC maintains accuracy for the entire life of the battery under all conditions, reserves energy to save data and never sacrifices run time.
