Image sensor family leads the way in next-generation ADAS safety

onsemi has launched its Hyperlux automotive image sensor family. With a 2.1µm pixel size, industry-leading 150dB ultra HDR and LED flicker mitigation (LFM) over the full automotive temperature range, the family delivers high performance, speed and advanced features to propel the next generation of ADAS forward. It also facilitates a smooth transition to Level 2+ driving automation, which needs the driver only to take over when alerted by the technology.

The family includes products with resolutions from 3MP to 8MP and higher, catering to sensing and viewing camera applications. With an HDR of 150dB, it captures high-quality images under extreme lighting conditions with no sacrificing lowlight sensitivity. The LFM capability of the platform provides that pulsed light sources do not appear to flicker, thereby avoiding flicker-induced machine vision issues.

“The simultaneous HDR and LFM capabilities ensure that the potential hazard can be identified in either very dark or bright scenes, critical to ADAS and in-cabin applications,” said Huohong Jiang, deputy general manager of the Intelligent Driving Sensor Business Unit at Desay SV. “With the new Hyperlux technology, automotive OEMs and tier ones can expect proven high performance in all operating conditions to accelerate more advanced safety and convenience features.”

The product family provides the industry’s lowest power consumption and smallest footprint. By utilising up to 30% less power and having up to 28% smaller footprint than competing devices, the automotive image sensors produce energy-efficient designs with the lowest system material cost.

“As vehicles become more connected and move closer to autonomy, the importance of safety and security is more critical than ever,” said Chris Adams, vice president, Automotive Sensing Division at onsemi. “Our knowledge of automotive applications and trends, along with our engineering expertise in image sensing, enable our customers to develop next-generation products that bring us closer to the Vision Zero initiative, a strategy to eliminate all traffic fatalities and severe injuries.”

The family is developed to fulfil the stringent safety necessities of ASIL D systems, while integrated security provides the highest coverage to cybersecurity threats. These sensors also supply a dual output stream at differing resolutions, permitting sensing and other functions to be performed simultaneously. Designers can profit from the flexible architecture for utilising a single camera for multiple functions, decreasing design time, risk and cost.
