BUILT-IN DELAY CIRCUIT HIGH-PRECISION VOLTAGE DETECTOR
S-809 Series
The S-809 Series is a high-precision voltage detector developed using
CMOS process. The detection voltage is fixed internally, with an
accuracy of
±
2.0%. Attachment of an external capacitor can delay the
release signal. Two output types, Nch open-drain and CMOS output,
are available.

Advantage over the S-808 Series
1.
Built-In delay circuit
Delay time setting by an additional external capacitor:
The S-809 can easily delay an release signal by attachment of an external capacitor with built-In delay circuit.
This results in an advantage of parts reduction over the S-808 Series.
