BQ2084-V143 描述
The bq2084-V143 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 bq2084-V143 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 bq29312 AFE protection IC to maximize functionality and safety and minimize component count and cost in smart battery circuits. Using information from the bq2084-V143, the host controller can manage remaining battery power to extend the system run time as much as possible.
The bq2084-V143 uses an integrating converter with continuous sampling for the measurement of battery charge and discharge currents
