Caution1. The above constants may be changed without 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 do not guarantee proper operation.
Perform through evaluation using the actual application to set the constant.
3. In the case of Nch open drain output, pull up CO pin by external resistor.
