- bq2083 and bq2085 Board Offset Characterization and CompensationPDF, 134 Kb, Archivo publicado: enero 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 SolutionsPDF, 571 Kb, Archivo publicado: marzo 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.

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 bq26500PDF, 185 Kb, Archivo publicado: enero 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
