SUPER-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR

Change of detection voltage
In Nch open-drain output products of the S-808 Series, detection voltage can be changed using resistance dividers
or diodes as shown in Figures 19 and 20. In Figure 19, hysteresis width is also changed.
n Remarks
In CMOS output products of the S-808 Series, through-type current flows when the device is detecting or releasing. If a high
impedance is connected to the input, oscillation may be caused due to the fall of the voltage by the through-type current when
lowering the voltage during releasing.
When designing for mass production using an application circuit described herein, take the product deviation and temperature
characteristic into consideration.
Seiko Instruments Inc. shall not bear any responsibility for the patents on the circuits described herein.

Note1: If RA and RB are large, the hysteresis width may be
larger than the value given by the formula above due
to through-type current (which flows slightly in Nch
open-drain circuit).
Note2: RA should be 75k
or less for purpose of protection
against oscillation.
