Example of Application Circuit

1. The Application to Microcomputer System

a. The input voltage detection type can be used as the voltage supervisor of microprocessor system like the

following circuit.

In this case, a detection power supply voltage is approximately 1.25

× (R1 + R2)/R2 (V).

The detecting supply voltage can be set between 2 V and 10 V.

b. The detecting voltage can be adjusted by changing R1 and/or R2 in the figure 1.

The detection accuracy is

±4%.

c. It has a delay capacitor and the delay time is about 200

µs.
