Remark
R1^*1
For power fluctuation
470 Ω
Set the value as small as possible to prevent deterioration
of the detection voltage.
C1
For power fluctuation
0.1 μF
Set R1 × C1 ≥ 40 × 10^−6.
ROUTn^*2
For output pin pull-up
100 kΩ
Make sure the power dissipation of the S-8229 Series is
not exceeded.
*1. Set up R1 as 100 kΩ or less to prevent oscillation.
*2. Set up each of ROUTn as 620 Ω or more so that the power dissipation is not exceeded.
Caution The above connection diagram and constant will not guarantee successful operation. Perform thorough
evaluation using the actual application to set the constant.
