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 32 to 33 . In Figure 32 , 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).
