SBS-Compliant Gas Gauge For Use With Bq29311

The BQ2083-V1P3 SBS-compliant gas gauge IC for battery pack or in-system installation maintains an accurate record of available charge in Li-ion or Li-polymer batteries. The BQ2083-V1P3 monitors capacity and other critical parameters of the battery pack and reports the information to the system host controller over a serial Communication bus. It is designed to work with the BQ29311 Analog front-end (AFE) protection IC to maximize functionality and safety and minimize component count and cost in smart battery circuits. Using information from the BQ2083-V1P3 the host controller CAN manage remaining battery power to extend the system run time as much as possible.
The BQ2083-V1P3 uses an integrating converter with continuous sampling for the measurement of battery charge and discharge currents. Optimized for coulomb counting in portable applications, the self-calibrating integrating converter has a resolution better than 3-nVh and an offset measurement error of less than 1-V (typical). For voltage and temperature reporting, the BQ2083-V1P3 uses a 16-bit A-to-D converter. In conjunction with the BQ29311 the onboard ADC also monitors individual cell voltages in a battery pack and allows the BQ2083-V1P3 to generate the control signals necessary to implement the cell balancing and the required safety protection for Li-ion and Li-polymer battery chemistries.
The BQ2083-V1P3 supports the Smart Battery Data (SBData) commands and charge-control functions. It communicates data using the System Management Bus (SMBus) 2-wire protocol. The data available include the battery?s remaining capacity, temperature, voltage, current, and remaining run-time predictions. The BQ2083-V1P3 provides LED Drivers and a push-button input to depict remaining battery capacity from full to empty in 20%, 25%, or 33% increments with a 3-, 4-, or 5-segment Display
The BQ2083-V1P3 contains 512 bytes of internal data Flash memory, which store configuration information. The information includes nominal capacity and voltage, self-discharge rate, rate compensation factors, and other programmable cell-modeling factors used to accurately adjust remaining capacity for use-conditions based on time, rate, and temperature. The BQ2083-V1P3 also automatically calibrates or learns the true battery capacity in the course of a discharge cycle from programmable near full to near empty levels.
The BQ29311 AFE protection IC provides power to the BQ2083-V1P3 from a 3 or 4 series Li-ion cell stack, eliminating the need for an external Regulator circuit.
