  • How to Generate Golden Image for Single-Cell Impedance Track(TM) Devices
    PDF, 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. This application report describes the necessary p
  • Host System Calibration Method (Rev. B)
    PDF, 140 Kb, Revision: B, File published: 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, File published: 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
