*1.

No overcharge detection / release hysteresis

*2.

The magnification of final overcharge is 1.11; the others are 1.25.

*3.

No final overcharging function

*4.

Refer to the *2 in the “ Operation”.

Remark 1.

Please contact our sales office for the products with detection voltage value other than those

specified above.

2.

The overdischarge detection voltage can be selected within the range from 1.7 to 3.0 V. When the

overdischarge detection voltage is higher than 2.6 V, the overcharge detection voltage and the

overcharge release voltage are limited as “Table 2”.
