Additional Details:

The XC61CC4002PR typically operates from a supply voltage close to its detection voltage. The output is held low when the input voltage is below the detection threshold and goes high (open) when the voltage is above the threshold. Detailed electrical characteristics, timing diagrams, and application circuits can be found in the Torex Semiconductor datasheet for this part. The specific package type and pinout configuration need to be considered for proper implementation. External pull-up resistor is needed for the output.
