HIGH-PRECISION VOLTAGE DETECTOR

S-807 Series

The S-807 Series is an adjustment-free high-precision voltage detector

made using the CMOS process. The output voltage is fixed internally,

with an accuracy of

±2.4%. Two output types are available, Nch open-

drain and CMOS output (active “H” and “L”), both of which have various

product lineups. This series features much lower current consumption

and higher detection voltage accuracy than the S-805 Series. Super-

miniature package is added for the S-807 Series, the S-807XXSX

Series.

This small SOT-23-5 style package allows the designer to

shrink the size of his finished product.

Electrical specs for the S-

807XXSX Series are the same as the standard S-807 Series. Output

forms of the S-807XXSX Series are Nch open-drain and CMOS active

“L”.
