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