FUNCTIONAL DESCRIPTION
General Operation
The bq2060A determines battery capacity by monitoring the amount of charge input or removed from a
rechargeable battery. In addition to measuring charge and discharge, the bq2060A measures battery voltage,
temperature, and current, estimates battery self-discharge, and monitors the battery for low-voltage thresholds.
The bq2060A measures charge and discharge activity by monitoring the voltage across a small-value series
sense resistor between the battery negative terminal and the negative terminal of the battery pack. The available
battery charge is determined by monitoring this voltage and correcting the measurement for environmental and
operating conditions.
