Application Notes

  • bq2083 and bq2085 Board Offset Characterization and Compensation
    PDF, 134 Kb, File published: Jan 30, 2004
    The bq208x (bq2083, bq2084, and bq2085) products are high-precision advanced gas gauge products for battery monitoring and management. Because the current signal ismeasured through a small sense resistor (< 20 m?? to minimize power loss, compensation for the ADC input offset is critical for the accuracy of the measurement. This application note discusses common issues associated with board offse
  • Cell-Balancing in the bq208x Advanced Gas Gauge Solutions
    PDF, 571 Kb, File published: Mar 17, 2004
    Serial connection of cells in a battery pack can result in reduced-capacity performance if some of the cells have different capacity or charge levels. The problem is that during charging or discharging of the pack, individual cell differences lead to different voltages ineach cell. Since the charger monitors only the summary voltage, some cells can be undercharged and others overcharged. Underch
  • Comparing the bq29312A to the bq29312
    PDF, 137 Kb, File published: Mar 7, 2005
    The bq29312A analog front end (AFE) IC contains a minor change to the existing bq29312 AFE that improves overall system-level ESD performance. The specifications of the bq29312 and bq29312A are identical.
  • Multicell Li-Ion and Li-Pol Battery Gas-Gauge Application Using bq26500
    PDF, 185 Kb, File published: Jan 29, 2004
    The bq26500 is the first complete battery fuel gauge for handheld devices such as PDAs and cellular handsets. Many of these applications use only one Li-Ion or Li-Polymer cell in the battery, producing a nominal 3.6 V. Although optimized for single-cell applications, the bq26500 works well in systems using multicell battery packs, particularly two series-cell batteries producing 7.2 V. This applic
