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 30 to
31
. In
Figure 30
, hysteresis width also changes.

should be 75 k
or less to prevent oscillation.
Caution If R
A
and R
B
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.
