Notas de aplicación

  • Single Cell Gas Gauge Circuit Design
    PDF, 154 Kb, Archivo publicado: feb 22, 2008
  • Theory and Implementation of Impedance Track Battery Fuel-Gauging Algorithm
    PDF, 608 Kb, Archivo publicado: enero 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.
