- bq2083, bq2084, and bq2085 Calibration Procedure (Rev. A)PDF, 69 Kb, Revisión: A, Archivo publicado: sept 15, 2004
This application report describes the optional calibration of the offsets, voltage, temperature, current, and coulomb counter in the bq2083, bq2084, and bq2085 advanced gas gauge devices. Addtional programming details and examples are provided in two appendixes. - Avoiding Clock Jitter with the bq2085 Advanced Gas GaugePDF, 147 Kb, Archivo publicado: oct 20, 2003
The internal-oscillator performance of the TI bq2085 advanced gas-gauge device depends on proper printed-circuit board layout of the external 113-kilohm resistor and phase-locked loop filter components. Component placement, grounding, and crosstalk avoidance must be carefully considered in the layout. - 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 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 application report describes a smart-battery charger reference design with a wide-input-voltage range. The reference design implements the System Management Bus (SMBus) protocol for communication between the MSP430 microcontroller and a SMBus-compatible battery fuel gauge. The MSP430 device interrogates the fuel gauge for voltage, current, and other parameters via SMBus. It then adjusts the p
