Application Circuit Examples
Microcomputer Reset Circuits
If the power supply voltage to a microcomputer falls below the specified level, an unspecified
operation may be performed or the contents of the memory register may be lost. When power supply
voltage returns to normal, the microcomputer needs to be initialized before normal operations can be
done. Reset circuits protect microcomputers in the event of current being momentarily switched off
or lowered.
Reset circuits shown in Figures 22 to 23 can be easily constructed with the help of the S-801 series
that has low operating voltage, a high-precision detection voltage, hysteresis, and a built-in delay
circuit.
