MANUAL RESET BUILT-IN DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING) HIGH-ACCURACY VOLTAGE DETECTOR
Rev.1.0_00
S-1003 Series
Seiko Instruments Inc.

Application Circuit Examples
1. Microcomputer reset circuits
In microcomputers, when the power supply voltage is lower than the guaranteed operation voltage, an unspecified
operation may be performed or the contents of the memory register may be lost. When power supply voltage
returns to the normal level, the microcomputer needs to be initialized. Otherwise, the microcomputer may
malfunction after that. Reset circuits to protect microcomputer in the event of current being momentarily switched
off or lowered.
Using the S-1003 Series which has the low operation voltage, a high accuracy detection voltage and hysteresis,
reset circuits can be easily constructed as seen in Figure 38 and Figure 39.
