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. - Single Cell Impedance Track Printed-Circuit Board LayoutPDF, 403 Kb, Archivo publicado: feb 22, 2008

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.

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 - How to Generate Golden Image for Single-Cell Impedance Track(TM) DevicesPDF, 964 Kb, Archivo publicado: enero 7, 2010
Texas Instruments advanced fuel gauges, employing the Impedance Trackв„ў algorithm, offer an unmatched array of features and benefits. Sometimes, however, the learning cycle to generate the golden image may seem a little challenging. In addition, determining the correct chemistry model and producing the golden image file can be time consuming.

To add improvements to the Impedance Trackв„ў algorithm, changes have been made to free up firmwarecode space. In the process of freeing up code space, the calibration calculations are no longerautomatically performed by the gauge but must be performed by the host and the results written back tothe gauge. This application note provides a flow on how to implement the calibration algorithm on a - Updating bq275xx Firmware at Production (Rev. A)PDF, 107 Kb, Revisión: A, Archivo publicado: feb 21, 2011
