Rev6.0
• 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 (V
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 status current consumption (I
to the Figure 11).
[Cause]
[Conclusion]
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in
• SII claims no responsibility for any and all disputes arising out of or in connection with any infringement
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.
If the load is taken off at least one time, the overcurrent is released and the overdischarge detection
works.
Unless keeping the IC with load for a long time, the reduction of battery voltage will be neglected,
because of the IC’s current consumption (typ. 7.5 μA) is small.
