sufficient evaluation using the actual application to set the constants.
Application Circuit Examples
1. 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 27 to 28 can be easily constructed with the help of the S-808xxC series,
that has low operating voltage, a high-precision detection voltage and hysteresis.
