(within 10 s). The time after V2 becomes the charger detection voltage (VCHA) until CO goes "L" is
the abnormal charge current detection delay time.
The abnormal charge current detection delay time has the same value as the over charge detection
delay time.
(10) Measurement Condition 10, Measurement Circuit 1 (Product with 0V battery charging function)
0V battery charge start charger voltage
Set V1=V2=0V and decrease V2 gradually. The voltage between VDD and VM when CO='H' (VM +
0.1 V or higher) is the 0V battery charge start charger voltage (V0CHA).
(11) Measurement Condition 11, Measurement Circuit 1 (Product with 0V battery charge inhibiting
function)
0V battery charge inhibiting battery voltage
Set V1=0V and V2=4V. Increase V1 gradually. The voltage between VDD and VSS when CO='H'
(VM + 0.1 V or higher) is the 0V battery charge inhibiting battery voltage (V0INH).

Description of Operation
Normal condition
This IC monitors the voltage of the battery connected to VDD and VSS pins and the differences in
voltages between VM and VSS pins to control charging and discharging. If the battery voltage is in
the range from the over discharge detection voltage (VDL) to the over charge detection voltage
(VCU), and the VM pin voltage is in the range from the charger detection voltage (VCHA) to the over
current 1 detection voltage (VIOV1) (the current flowing through the battery is equal to or lower than a
specified value), both the charging and discharging control FETs turn on. In this condition, charging
and discharging can be carried out freely. This condition is called the normal condition.
Over current condition
If the discharging current becomes equal to or higher than a specified value (the VM pin voltage is
equal to or higher than the over current detection voltage) during discharging under normal condition
and it continues for the over current detection delay time or longer, the discharging control FET turns
off to stop discharging. This condition is called an over current condition. (The over current means
