HIGH-PRECISION VOLTAGE DETECTOR

3. Change of detection voltage
In Nch open-drain output products of the S-807 Series, detection voltage can be changed with resistance dividers or diodes
as shown in Figures 29 and 30. In Figure 29, hysteresis width is also changed.
Notes
In CMOS output products of S-807 Series, high through current flows when detecting or releasing. If a high impedance is
connected to the input, oscillation may be caused by the through current when lowering the voltage during releasing.
In TO-92 products, since there are projections and resin burrs on the roots of the lead terminals formed at the Tiebar-cut, do
not solder to them.
When designing for mass production using an application circuit described here, take into account the deviation of
components and temperature characteristics.
Seiko Instruments Inc. cannot take any responsibility for the patents on the circuits described here.
