3. Change of Detection Voltage
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.

RA should be 75 k
Ω or less to prevent oscillation.
Caution If RA and RB are large, the hysteresis
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).

Caution The above connection diagram and constants do not guarantee correct operation. Perform
sufficient evaluation using the actual application to set the constants.
