Table 3 describes the bq2084-V140 registers. Figure 1. bq2084-V140 Gas Gauging Operational Overview The bq2084-V140 accumulates a measure of charge and discharge currents and estimates self-discharge of the battery. The bq2084-V140 compensates the charge current measurement for temperature and state-of-charge of the battery. The bq2084-V140 also adjusts the self-discharge estimation based on temperature. The main charge counter RemainingCapacity() (RM) represents the available capacity or energy in the battery at any given time. The bq2084-V140 adjusts RM for charge, self-discharge, and other compensation factors. The information in the RM register is accessible through the SMBus interface and is also represented through the LED display. 9 Submit Documentation Feedback |
