The above figure shows the MC34161 configured as a dual positive overvoltage detector. As the input voltage increases from ground, the LED will turn ‘ON’ when
V
or V
exceeds V
. With the dashed line output connection, the circuit becomes a dual positive undervoltage detector. As the input voltage decreases from
the peak towards ground, the LED will turn ‘ON’ when V
S1
or V
S2
falls below V
1
.
For known resistor values, the voltage trip points are:
For a specific trip voltage, the required resistor ratio is:
