Description

The bq2016 gas gauge IC for battery pack or in-system installation maintains an accurate record of available battery capacity. To integrate charge and discharge activity of the battery, the IC monitors a voltage drop across a sense resistor connected in series with the cells of the battery. The bq2016 compensates for battery temperature, charge/discharge rate, and battery self-discharge to the charge counter to provide available-capacity information across a wide range of operating conditions. The bq2016 works with NiCd or NiMH battery packs that have a capacity of 1 to 4.5 Ah and that are designed for high discharge rate applications such as power tools.

The VPFC input sets the initial full charge reference of the battery pack.
