Abstract: A sensor includes a MEMS element responsive to acceleration, an analog-to-digital converter coupled to an output of the MEMS element, and a free fall detector coupled to an output of the analog-to-digital converter. The free fall detector is configured to determine whether the sensor is in free fall based on acceleration information received from the analog-to-digital converter. A digital interface is coupled to the analog-to-digital converter and to an output of the free fall detector and is configured to issue an output related to free fall information determined by the free fall detector.
