Caution 1. It is recommended that filter constants between VDD pin and VSS pin should be set
approximately to 47 μF • Ω.
e.g., C_VSS × R_VSS = 1.0 μF × 47 Ω = 47 μF • 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.
2. It has not been confirmed whether the operation is normal in circuits other than the above
example 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 constants.
Remark Refer to the application note for constants of each external component.
