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. - Single Cell Impedance Track Printed-Circuit Board LayoutPDF, 403 Kb, Datei veröffentlicht: Feb 22, 2008

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 - ESD and RF Mitigation in Handheld Battery Pack ElectronicsPDF, 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
