Advanced driver assistance systems (ADAS) have become standard features in modern vehicles, enhancing driving safety and comfort. The ADAS functions include not only the classic emergency braking function realized by the windshield camera, but also the multi-camera surround view + perception system with integrated parking assistance functions. These systems rely on image sensors ranging from 1 million to 8 million pixels to support both visual and perceptual functions simultaneously. However, automakers (Oems) and Tier 1 suppliers are confronted with a challenge: they must provide high-performance and highly reliable imaging solutions to meet strict safety standards and regulatory requirements, while also taking into account cost, space optimization and design flexibility.

onsemi's 3-megapixel sensor Hyperlux™ AR0341AT is an excellent choice for mainstream ADAS applications. This article will explore the six core advantages of this sensor and interpret how it strikes a balance among performance, reliability and efficiency.

Excellent low-light performance

ADAS sensors need to operate reliably under various lighting conditions, especially at night or in low-light environments. The AR0341AT adopts a 2.1 µm overexposure pixel architecture, achieving excellent low-light sensitivity without increasing the sensor size. This feature enables the compact camera module to capture clear and low-noise images, which is crucial for detecting pedestrians, high-speed vehicles or road hazards in dim environments - while avoiding the increased cost and design complexity associated with larger sensors.

Leading high dynamic range (HDR

Sudden changes in light (such as when entering and exiting tunnels) not only affect human vision but also interfere with the performance of cameras. Traditional multi-exposure HDR technology often has flaws due to motion blur or delay issues, posing a threat to safety.

The AR0341AT has overcome this challenge with an HDR capability of up to 150 dB, capable of simultaneously maintaining image clarity in both bright and dark areas. This ensures that the system performance remains consistently stable under dynamic lighting conditions, reducing the risk of missed detections due to overexposure or underexposure.

Ultra-low power consumption

Power supply efficiency is becoming increasingly crucial nowadays, especially for electric vehicles (EVs) equipped with all-weather camera security features. The AR0341AT adopts a truly low-power design, minimizing battery consumption while maintaining full-function operation.

Lower power consumption can also reduce heat load, simplify system heat dissipation design, and support the use of smaller and more cost-effective modules and lenses. This series of advantages translates into greater design flexibility, more reliable system performance, and longer component lifespan.

Compact, exquisite and easy-to-design form factor

Modern vehicle design demands that technological integration be simple, understated and not conspicuous. Bulky sensors will limit the choice of installation positions and even damage the overall aesthetic appeal of the vehicle.

Thanks to its 2.1 µm pixel size, the AR0341AT is much smaller than similar 3.0 µm sensors. This compact size enables the camera module to be made thinner and lighter, seamlessly integrating with the vehicle's exterior design without compromising performance in the slightest.

Reliable thermal stability

The ADAS system must be able to operate stably within an extremely wide temperature range, maintaining outstanding performance in both the low-temperature environment of winter and the high-temperature conditions of midsummer. Many sensors will struggle to maintain image quality under thermal stress, thus posing safety hazards.

This 3-megapixel sensor, Hyperlux, features automotive-grade durability and can provide consistent image quality even within extreme temperature ranges. Its well-tested thermal stability enables it to handle various harsh environments around the world with ease.

Proven quality and long-term support

In the automotive industry, reliability and long-term support are uncompromising hard requirements. Automobile manufacturers (Oems) need to ensure that the components they currently select will continue to receive support for many years to come.

onsemi has been deeply engaged in the automotive imaging field for decades. The profound experience it has accumulated has injected solid confidence into the Hyperlux sensor AR0341AT, enabling it to handle the demanding requirements of today's ADAS applications with ease. Relying on a mature product roadmap and a stable supply record, onsemi gives Oems and Tier 1 suppliers peace of mind: their designs will receive long-term support, allowing them to rest easy.

Core advantages: Outstanding performance, no compromise required

The 3-megapixel Hyperlux sensor AR0341AT achieves a rare combination of high performance, compact design, low power consumption and long-term reliability. It enables Oems and Tier 1 suppliers to create smarter, safer and more efficient ADAS systems without compromising in any aspect throughout the process.

In a market where cost pressure is real, true value does not stem from the lowest price, but from the best cost performance. This 3-megapixel Hyperlux sensor can bring about tangible cost savings throughout the entire product life cycle, making it highly suitable for mainstream ADAS applications.
