SUPER-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR
S-808 Series

Seiko Instruments Inc.
Application Circuit Examples
1.
Microcomputer reset circuits
If the power supply voltage to a microcomputer falls below the specified level, an unspecified operation may be performed or
the contents of the memory register may be lost. When power supply voltage returns to normal, the microcomputer needs to
be initialized before normal operations can be done.
Reset circuits protect microcomputers in the event of current being momentarily switched off or lowered.
With the S-808 Series which has a low operating voltage, a high-precision detection voltage and hysteresis characteristic, the
reset circuits shown in Figures 19 to 20 can be easily constructed.
2.
Addition of power-on reset circuit
A power-on reset circuit can be constructed using Nch open-drain product of S-808 Series.

Note 2:
R should be 75 k
or less for purpose of protection against oscillation.
Di instantaneously discharges the electric charge stored by C at the falling of the power.
Di is not necessary if delay in falling time is normal.

Note 3: When the power steeply rises, output may goes high for a instant due to the IC inconstant region
characteristics (output voltage is unstable in the region under minimum operating voltage) as shown in
Figure. 26.
