Figure 3. bq2083V1P2 Operational Overview
The bq2083V1P2 accumulates a measure of charge and discharge currents and estimates self-discharge of the
battery. The bq2083V1P2 compensates the charge current measurement for temperature and state-of-charge of
the battery. The bq2083V1P2 also adjusts the self-discharge estimation based on temperature.
