Onsemi recently launched the Hyperlux LP image sensor family, targeting industrial and commercial cameras such as smart doorbells, security cameras, AR/VR/XR headsets, machine vision and video conferencing. The 1.4-µm pixel sensors can extend battery life by up to 40%, based on the company’s internal tests, with low power consumption and wake-on-motion features, and deliver high image quality even in challenging lighting conditions.
The product family, consisting of three new devices, features a stacked architecture design that minimizes size, with the smallest device nearly the size of a grain of rice. The new devices include the 20-megapixel (MP) AR2020, the 8-MP AR0830 and the 5-MP AR0544.

Particularly for applications that use cameras for security, the biggest requirements are for better image quality, higher reliability and longer battery life. “With the image sensors, cameras can deliver clearer images and more accurate object detection even in harsh weather and lighting conditions,” onsemi said. “Additionally, these cameras are often placed in locations that can be difficult to access to replace or recharge batteries, making low power consumption a critical feature.”
The Hyperlux LP family offers several features and proprietary technologies that improve performance and resolution. These include wake on motion that enables sensors to operate in low-power mode until it detects movement, a smart region of interest that provides a context view of the scene at reduced bandwidth and a separate region of interest in the original detail, and near-infrared (NIR) performance for higher image quality.
Onsemi also said the Hyperlux LP family’s low-power consumption reduces thermal noise that can negatively impact image quality and eliminates the need for heat sinks. These image sensors will be available in the fourth quarter of 2023.
