BUILT-IN DELAY DIRCUIT HIGH-PRECISION VOLTAGE DETECTOR
S-809 Series
Seiko Instruments Inc.

Application Circuit Examples
1.
Microcomputer reset circuits
With the S-809 Series which has a low operating voltage, a high-precision detection voltage and hysteresis characteristic, the
reset circuits shown in Figures 22 to 23 can be easily constructed.
2.
Change of detection voltege
In Nch open-drain output products of the S-809 Series, detection voltage can be changed using resistance dividers or diodes
as shown in Figures 24 and 25. In Figure 24, hysteresis width is also changed.
Notes
In CMOS output products of the S-809 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 to prevent oscilation.
