The above figure shows the MC34161 configured as a positive voltage window detector. This is accomplished by connecting channel 1 as an undervoltage detector,
and channel 2 as an overvoltage detector. When the input voltage V
S
falls out of the window established by V
and V
, the LED will turn ‘ON’. As the input voltage
falls within the window, V
increasing from ground and exceeding V
, or V
decreasing from the peak towards ground and falling below V
3
, the LED will turn ‘OFF’.
With the dashed line output connection, the LED will turn ‘ON’ when the input voltage V
S
is within the window.
For known resistor values, the voltage trip points are:
For a specific trip voltage, the required resistor ratio is:
