DESCRIPTION
The bq2083- V1P3 SBS-pliant 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 munication bus. It is designed to work with the bq29311 analog front-end (AFE) protection IC to maximize functionality and safety and minimize ponent 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...
