Window Comparator/Voltage Sensitive Switch TLV1701

Window Comparator/Voltage Sensitive Switch TLV1701

This circuit utilizes two comparators in parallel to determine if a signal is between two reference voltages. If the signal is within the window, the output is high. If the signal level is outside of the window, the output is low. For this design, the reference voltages are generated from a single supply with voltage dividers.

This 5V single-supply window comparator utilizes a dual open-collector comparator and two trimmer potentiometer to set the  window voltage. 2X TLV1701 was used in this design due to its low power consumption and open collector output, which allows the output to be pulled up as high as 36 V.
