Additional Details:

The XC6385A351PR has a detection voltage of 3.5V. The suffix PR likely indicates specific packaging and tape options. The output is typically an N-channel open drain, which requires a pull-up resistor. This device is designed to operate over a wide temperature range, generally -40°C to +85°C. The inclusion of hysteresis improves the stability of the output signal, preventing false triggering due to noise.
