3 Possible Overcharge

The BQ25172 has features to prevent overcharge of the battery. When charge is enabled the battery voltage is checked, if the cell voltage is over 1.33V/Cell the battery is considered full and the charge does not start. When the battery voltage decreases, a charge cycle starts.
