ULC1001-DRV290x Evaluation Module
Texas Instruments created the Ultrasonic Lens Cleaning (ULC) system for removing water, ice, or other
contaminants from automotive, security, and industrial lens systems. Ultrasonic Lens Cleaning improves visibility
by efficiently clearing water, ice, and some contaminants. For some use cases, Ultrasonic Lens Cleaning
eliminates the need for washer tubes, spray nozzles, or wipers. The ULC System is an electromechanical
system composed of a piezo based lens cover or lens system, housing, and ULC1001-DRV290x EVM. The
ULC1001-DRV290x EVM is the electrical system developed to excite the Lens Cover and expel contaminants.
