VOLTAGE DETECTOR
S-806 Series
The S-806 Series is a non-adjusting voltage detector made using a
CMOS process. The voltage detectors are composed of a high-
precision and low power consumption standard voltage source, a
comparator, a hysteresis circuit, and an output driver. The detection
voltage is fixed internally, and the output form is Nch open-drain.
This series has various product line up.
