HIGH-PRECISION VOLTAGE DETECTOR
S-807 Series
1.4 Operating margins of power and minimum operating voltage
of CPU are close
Set the voltage so that it will be detected between the power
voltage and the minimum operating voltage of the CPU.
Thus, if two voltage points to be detected are very close, the
voltage between those two points must be detected
correctly. The S-807 Series offers an excellent detection
voltage precision, so the voltage between narrow limits can
be detected correctly.

2. Others
2.1 Low current consumption
The current consumption is half of that of a conventional voltage detection IC, so the battery service life can be
prolonged.
2.2 Wide operating voltage range
The maximum operating voltage of a conventional IC is 10 V. For the S-807 Series, the maximum detectable voltage
has been increased to 15 V.
