BATTERY PROTECTION IC FOR 2-CELL SERIAL PACK

After the overcurrent detection, the load was connected for a long time, even if one of the battery voltage
became lower than overdischarge detection voltage (VDD1, 2), the IC can’t detects the overdischarge as
long as the load is connected. Therefore the IC’s current consumption at the one of the battery voltage is
lower than the overdischarge detection voltage is same as normal condition current consumption (IOPE)
(refer to the Figure 10) .

The battery voltage is less than the overdischarge

As long as the load is connected, the IC ’s current is

[Cause]
The reason is as follows. If the overcurrent detection and overdischarge detection occur at same time,
the overcurrent detection takes precedence the overdischarge detection. As long as the IC detects
overcurrent, the IC can’t detect overdischarge.
[Conclusion]
If the load is taken off at least one time, the overcurrent is released and the overdischarge detection
works.
Unless keeping the IC (S-8232 Series) with load for a long time, the reduction of battery voltage will be
neglected, because of the IC’s (S-8232 Series) current consumption (typ. 7.5
A) is small.
Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in
electrostatic protection circuit.
