Advanced Driver Assistance Systems (ADAS) and autonomous driving (AD) systems utilize cameras and LiDAR sensors to acquire critical data to enable safety features such as automated cruise control, automatic emergency braking, lane keep assist, automatic lane keeping systems, advanced front lighting, windshield wiper control, automatic low and high beam switching, etc. Because these sensors are integral to safety systems, they must be ASIL Functional Safety (ISO-26262) and AEC-Q100 Grade 2 compliant. onsemi’s automotive-grade image sensors and silicon photomultipliers (SiPMs) are the core sensing components of cameras and LiDARs respectively.
