EXAMPLE OF APPLICATION CIRCUIT 1) The application to microprocessor system Note 1. 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 x (R1+R2)/ R2 (v). The detecting supply voltage can be set between 2V and 10V. Note 2. The detecting voltage can be adjusted by changing R1 and/or R2 in the following circuit. The detection accuracy is 4%. Note 3. It has a delay capacitor and the delay time is about 200s.
