2. It is recommended that filter constants between VDD and VSS should be set approximately to 47 µF
3. It has not been confirmed whether the operation is normal in circuits other than the above example

• Ω.
Sufficient evaluation of transient power supply fluctuation and overcurrent protection function with
the actual application is needed to determine the proper constants. Contact our sales office in case
the constants should be set to other than 47 µF • Ω.
of connection. In addition, the example of connection shown above and the constants do not
guarantee proper operation. Perform thorough evaluation using an actual application to set the
constant.
