Description

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.

Features
  • Two ultrasonic sensor channels
  • Operates from a 12V automotive battery
  • Detects kicks for distances up to 50cm
  • Low quiescent current
  • Design has been tested and includes schematics, layout, and test results
