    PDF, 608 Kb, File published: Jan 31, 2008
    This application report outlines the theory of Impedance Trackв„ў (IT) technology used in the bq2750x series of fuel gauge ICs for single-cell Li-ion applications (e.g., smart phones, media players, and PDAs). The implementation of the IT algorithm in the bq2750x family is reviewed, and the settings of data flash constants associated with the fuel-gauging algorithm is described in detail.

    The Texas Instruments Impedance Trackв„ў (IT) fuel gauge is designed for reporting remaining battery capacity and run time accurately. To effectively accomplish this reporting a real application environment must be used for test results. The test board should be designed as similar to the real application circuit as possible. This application report outlines the procedure for implementing an accurac

    The bq275xx gas gauge integrated circuits (IC) can use an I2C line for communication with the host system. It is necessary to allow application-layer software on the host system to access parameters made available by the gas gauge IC. Multiple levels of abstraction are between the gauge and a given application. This document describes an example implementation of each of these layers in an effo
