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
