Precautions
If a charger is connected in the over discharge condition and one of the battery voltages becomes
equal to or higher than the over charge release voltage (VCU) before the battery voltage which is
below the over discharge detection voltage (VDD) becomes equal to or higher than the over
discharge release voltage (VDU), the over discharge and over charge conditions are entered and
the charging and discharging FETs turn off. Both charging and discharging are disabled. If the
battery voltage which was higher than the over charge detection voltage (VCU) falls to the over
charge release voltage (VCD) due to internal discharging, the charging FET turns on.
If the charger is detached in the over charge and over discharge condition, the over charge
condition is released, but the over discharge condition remains. If the charger is connected again,
the battery condition is monitored after that. The charging FET turns off after the over charge
detection delay time, the over charge and over discharge conditions are entered.
If any one of the battery voltages is equal to or lower than the over discharge release voltage (VDU)
when they are connected for the first time, the normal condition may not be entered. If the VMP
terminal voltage is made equal to or higher than the VCC voltage (if a charger is connected), the
normal condition is entered.
If the CTL terminal floats in power-down mode, it is not pulled up in the IC, charging may not be
inhibited. However, the over discharge condition becomes effective. At that time, current
consumption would be increase because CTL terminal is affected by noise. If the charger is
connected, the CTL terminal is pulled up, and charging and discharging are inhibited immediately.
