MOTOROLA ANALOG IC DEVICE DATA
The above figure shows the MC34161 configured as an overvoltage detector with an audio alarm. Channel 1 monitors input voltage VS while channel 2 is connected
as a simple RC oscillator. As the input voltage increases from ground, the output of channel 1 allows the oscillator to turn ‘ON’ when VS exceeds V2.
For known resistor values, the voltage trip points are:
For a specific trip voltage, the required resistor ratio is:

The above figure shows the MC34161 configured as a microprocessor reset with a time delay. Channel 2 monitors input voltage VS while channel 1 performs the time
delay function. As the input voltage decreases towards ground, the output of channel 2 quickly discharges CDLY when VS falls below V1. As the input voltage increases
from ground, the output of channel 2 allows RDLY to charge CDLY when VS exceeds V2.
For known resistor values, the voltage trip points are:
For a specific trip voltage, the required resistor ratio is:
