With a 2.1 µm pixel size, industry-leading 150dB ultra high dynamic range (HDR) and LED flicker mitigation (LFM) across the full automotive temperature range, onsemi’s new Hyperlux image sensor family provides the performance, speed and advanced features to propel the next generation of Advanced Driver Assistance Systems (ADAS) forward. The sensors also enable a smooth transition to Level 2+ driving automation.

The Hyperlux family spans products with resolutions from 3 to 8 megapixel (MP), catering to both sensing and viewing camera applications. With an HDR of 150 dB, it captures high quality images under the most extreme lighting conditions without sacrificing lowlight sensitivity. The simultaneous HDR and LFM capabilities ensure that potential hazards can be identified in either very dark or bright scenes – a capability critical to ADAS as well as in-cabin applications. The LFM capability of the platform ensures that pulsed light sources do not appear to flicker and thereby avoids flicker-induced machine vision issues.

According to onsemi, the Hyperlux product family boasts the industry’s lowest power consumption and smallest footprint. By using up to 30% less power and having an up to 28% smaller footprint than competing devices, the automotive image sensors enable energy-efficient designs at low system material cost. As more electronic content, including image sensors, gets added to cars, it is crucial that the content is as small as possible to fit in existing designs while not disrupting the internal and external style of the vehicle.

Hyperlux is designed to meet the stringent safety requirements of Automotive Safety Integrity Level D (ASIL D) systems, while integrated security gives the highest coverage to cybersecurity threats. These sensors also offer a dual output stream at differing resolutions, allowing sensing and other functions to be performed simultaneously. Designers can benefit from the flexible architecture for the use of a single camera for multiple functions, reducing design time, risk and cost. The first two sensors of the Hyperlux product family, AR0823AT and AR0341AT, are now sampling for early access customers.
