HIGH-PRECISION VOLTAGE DETECTOR
S-807 Series
Application Circuit Examples
1. Reset circuits of microcomputers
If the power supply voltage to a microcomputer falls below the specified level, unspecified operation may be performed or the
contents of the memory register may be lost. When power supply voltage returns to normal, the microcomputer may need to
be initialized before normal operations can be done.
Reset circuits protect microcomputers, in the event of current being momentarily switched off or lowered.
With the S-807 Series, the reset circuits shown in Figures 24 to 26 can be easily constructed.
