Melexis ToF sensors help enable functional safety applications

Update time : 2023-06-23 14:50:17

Tessenderlo, Belgium, June 20, 2023 - Melexis expands its product range and further strengthens its position in the field of time-of-flight (ToF) technology. The newly launched MLX75027RTI helps automotive and industrial customers meet functional safety requirements.

The MLX75027RTI is a VGA resolution ToF sensor chip with 307k pixel spatial resolution and is ASIL compliant for safety critical systems requiring ASIL or SIL certification. Key applications for this sensor chip include dynamic airbag suppression (ensuring that airbags do not deploy when not necessary), driver attention monitoring, and external proximity LiDAR. It is also used in industrial cameras to provide safety perimeters, to support robotic motion control, and to enable more advanced machine vision technologies.
At the heart of the MLX75027RTI is backside illumination (BSI) imaging technology that combines Melexis' expertise in automotive applications with Sony's proprietary DepthSense® ToF pixel architecture. the MLX75027RTI delivers 135 depth frames per second.
In terms of packaging, the sensor chip is 50% smaller than existing versions of the device, supporting the development of imaging systems with more compact dimensions. The integrated MLA (microlens array) main light angle has been optimized to simplify the entire optical system. The new MLX75027 is available in both automotive and industrial versions. The MLX75027RTI is designed for automotive applications with an operating temperature range of -40˚C to +105˚C, while the MLX75027STI is suitable for industrial applications with an operating temperature range of -20˚C to +85˚C. proven daylight robustness, which means that signal quality is unaffected by the external environment.
"The upcoming NCAP regulations will drive the use of in-vehicle monitoring in safety applications, which will also become increasingly important in industrial and mass market applications," said Gualtiero Bagnuoli, marketing manager for optical sensor chips at Melexis, "Our time-of-flight sensor chip family is already widely used. Now, with the introduction of the MLX75027RTI, we will provide support for the safe integration of system-level functions."
