DESCRIPTION

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.
