This reference design uses ultrasonic sensing to detect a kicking motion indicating the user's desire to activate a power lift-gate, power trunk, or power sliding door on an automobile. Ultrasonic sensing allows detection of more than one object, and gives a measure of distance to each object. The high-resolution and low power dissipation make this design suitable for automotive hands-free closure systems where gesture detection and low current from the battery are critical.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
