MOTOROLA ANALOG IC DEVICE DATA
The above figure shows the MC34161 configured as a positive and negative overvoltage detector. As the input voltage increases from ground, the LED will turn ‘ON’
when either –VS1 exceeds V2, or VS2 exceeds V4. With the dashed line output connection, the circuit becomes a positive and negative undervoltage detector. As the
input voltage decreases from the peak towards ground, the LED will turn ‘ON’ when either VS2 falls below V3, or –VS1 falls below V1.
For known resistor values, the voltage trip points are:
For a specific trip voltage, the required resistor ratio is:
