Product Description

The BQ27210DRKR is a highly accurate stand-alone single-cell Li-ion and Li-polymer Battery Capacity Monitoring and Reporting Device targeted at space-limited, portable applications. The IC monitors a voltage drop across a small current sense resistor connected in series with the battery to determine charge and discharge activity of the battery. Compensations for battery age, temperature, self-discharge and discharge rate are applied to the capacity measurements to provide available time-to-empty information across a wide range of operating conditions. Battery capacity is automatically recalibrated, or learned, in the course of a discharge cycle from full to empty. Internal registers include current, capacity, time-to-empty, state-of-charge, cell temperature and voltage, status and more. The bqJUNIOR can operate directly from single-cell Li-ion and Li-polymer batteries and communicates to the system over a HDQ one-wire or I²C serial interface.
