FUNCTION
Each cell in a multiple-cell pack is compared to an
internal reference voltage. If one cell reaches an
overvoltage condition, the protection sequence
begins. The bq2941x device starts charging an
external capacitor through the CD pin. When the CD
pin voltage reaches 1.2 V, the OUT pin changes
from a low level to a high level.
