Caution
1. The above constants are subject to change without prior notice.
2. It has not been confirmed whether the operation is normal or not in circuits other than the above
example of connection. In addition, the example of connection shown above and the constant
will not guarantee successful operation. Perform thorough evaluation using the actual
application to set the constant.
3. Set the same constants to R1, R2 and to C1, C2 and CVDD.
4. Set RVDD, C1, C2, and CVDD so that the condition (RVDD) × (C1, C2, CVDD) ≥ 5 × 10^−6 is satisfied.
5. Set R1, R2, C1, C2, and CVDD so that the condition (R1, R2) × (C1, C2, CVDD) ≥ 1 × 10^−4 is satisfied.
6. Since CO pin may become detection status transiently when the battery is being connected,
connect the positive terminal of BAT1 last in order to prevent the three terminal protection fuse
from cutoff.
