Precautions
After the overcurrent detection delay, if the battery voltages is equals the overdischarge detection voltage
(VDD1,2) or lower, the overdischarge detection delay time becomes shorter than 10ms (min.). It occurs
because capacitor C3 sets all of delay times (refer to the Figure 8) .

The over current delay
The over discharge delay
The delay time becomes shorter than typical
The battery voltage is equal to
or less the overdischarge voltage (VDD)
after stopping the overcurrent.
Figure 8
[Cause]
When overcurrent detection is released until tIOV1, the capacitor C3 is charged by S-8232 Series. If all
battery voltage is lower than VDD1, 2 at that time, charging goes on. So delay time is shorter than
typical.
[Conclusion]
This phenomenon occurs when all battery voltage is nearly equal to the overdischarge voltage (VDD1, 2)
after overcurrent detected. It means that the battery capacity is small and those must be charged in
the future. Even if the state changes to overdischarge condition, the battery package capacity is same
as typical.
When one of the battery voltages is overdischarge detection voltage (VDD1, 2) or lower and the other one
becomes higher than the overcharge detection voltage (VCU1, 2), the IC detects the overcharge without the
overcharge detection delay time (tCU) (refer to the Figure 9) .

[Cause]
It is same as the overdischarge detection under the overcurrent condition. It occurs because capacitor
C3 sets all of delay times.
[Conclusion]
This phenomenon occurs when one battery voltage is lower than overdischarge voltage (VDD1, 2) and
batteries are charged by charger. Since voltage difference between two batteries is large in this
situation, the S-8232 Series immediately stops the charging of the other battery to reduce voltage
difference. This action improves the safety of a battery pack and dose not do any harm to the pack.
