- Do not connect
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 pensates for battery temperature, charge/discharge rate, and battery self-discharge to the charge counter to provide availablecapacity information across a wide range of operating conditions. The bq2016 works with Ni Cd or Ni MH 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. The bq2016 learns the true discharge capacity of the battery pack and automatically updates the full-charge reference during the course of a discharge cycle from full to empty. The remaining capacity is reported as the ratio...
