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, 档案已发布: 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. 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, 修订版: A, 档案已发布: Feb 21, 2011
