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.

If the voltage at the CD pin, VCD, reaches 1.2 V, the OUT pin is activated and transitions high. An externally connected NCH FET is activiated and blows the external fuse in the positive battery rail; see the functional block diagram. If all cell voltages fall below V(PROTECT) before the voltage at pin CD reaches 1.2 V, the delay time does not run out. An internal switch clamps the CD pin to GND and discharges the capacitor, C(DELAY), and secures the full delay time for the next occurring overvoltage event. Once the pin OUT is activated, it transitions back from high to low after all battery cells reach V(PROTECT)– Vhys.
