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 V
exceeds V
, or V
exceeds V
. 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 V
S2
falls below V
3
, or V
S1
falls below V
1
.
For known resistor values, the voltage trip points are:
For a specific trip voltage, the required resistor ratio is:
