VDD
VSS
In Nch open-drain output products of the S-808xxC series, detection voltage can be changed using
resistance dividers or diodes as shown in Figures 30 to 31 . In Figure 30 , hysteresis width also changes.
Caution The above connection diagram and constants do not guarantee correct operation. Perform

should be 75 kΩ or less to prevent oscillation.
Detection
width may aloso be larger than the value
given by the above equation due to the
through-type current (which flows
slightly in an Nch open-drain product).
