VSS
In Nch open-drain output products of the S-809xxC Series, detection voltage can be changed using
resistance dividers or diodes as shown in Figures 29 to 30. In Figure 29, hysteresis width also changes.
A
should be 75 kΩ or less tp prevent oscillation.
Perform through evaluation using the actual application to set the constant.

width may also be larger than the value
given by the above equation due to
