  Theory and Implementation of Impedance Track Battery Fuel-Gauging Algorithm
  PDF, 608 Kb, Datei veröffentlicht: 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.

  Impedance Track Fuel Gauge Accuracy Test for GSM Phone Applications
  PDF, 393 Kb, Datei veröffentlicht: Mar 21, 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. This application report outlines the procedure for implementing an accurac

  WinCE/Linux Drivers for bq275xx Fuel Gauge
  PDF, 188 Kb, Datei veröffentlicht: 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

  Host System Calibration Method (Rev. B)
  PDF, 140 Kb, Revision: B, Datei veröffentlicht: May 19, 2016
  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

  ESD and RF Mitigation in Handheld Battery Pack Electronics
  PDF, 68 Kb, Datei veröffentlicht: Mar 6, 2008
  It is imperative to protect the electronics in a consumer-removable battery pack from ESD damage. Even an upset without permanent damage may be unacceptable to the end-user. Handheld equipment that contains a transmitter also may require protection to guard against improper measurement and/or upset due to the affect of the radio frequency (RF) on the circuitry. Because the RF field strength varies
