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”.
