BQ27200DRKR - TI Function Overview

The BQ27200DRKR is a stand-alone highly accurate single-cell Li-ion and Li-pol battery gas gauge Integrated Circuit with I²C interface 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 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.
Reports accurate time-to-empty with measured load and historical maximum and standby loads
Reports temperature, voltage and current
High accuracy charge and discharge current integration with automatic offset calibration
Requires no user calibration
Programmable input/output port
Internal user EEPROM configuration memory
