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, File published: Jan 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.
