Abstract
A sensor interface circuit for a vehicle includes a signal conditioning module having at least one raw sensor signal input, and at least one conditioned sensor signal output, and a differential comparator module including a differential comparator and an adaptable hysteresis module. The adaptable hysteresis module provides a first hysteresis magnitude to the differential comparator when a sensor signal is below a threshold and a second hysteresis magnitude to the differential comparator when the sensor signal is above the threshold.
