According to user’s selection of the function to charge 0 V battery, either function of Charger voltage
for start charging 0 V battery or Battery voltage for inhibit charging 0 V battery is applied to each
product.
In this Charger voltage for start charging 0V battery, when V1 = V2 = V3 = V4 = 0 V, V
max., the COP pin’s voltage is V
In this Battery voltage for inhibit charging 0 V battery, when V1 = V2 = V3 = V4 = V
V, the COP pin’s voltage is V
