Precautions
Caution 1. The above constants may be changed without notice.
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 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 (V
below the over discharge detection voltage (

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 and discharging
may not be inhibited. However, the over discharge condition becomes effective. If the charger is
connected, the CTL terminal is pulled up, and charging and discharging are inhibited immediately.
Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in
electrostatic protection circuit.
