Application Circuit Examples
ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR WITH DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING)
Figure 25 Measuring Conditions of Delay Time
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-809xxC Series
that has a low operating voltage, a high-precision detection voltage, hysteresis and the reset circuits.
