  • 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.
