  Theory and Implementation of Impedance Track Battery Fuel-Gauging Algorithm
  PDF, 608 Kb, 档案已发布: 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.

  WinCE/Linux Drivers for bq275xx Fuel Gauge
  PDF, 188 Kb, 档案已发布: Mar 17, 2011
  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

  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
