Melexis rolls automotive single-chip time-of-flight sensor
With the MLX75027, chipmaker Melexis is introducing an improved and enhanced version of a Time-of-flight sensor developed in 2014 by SoftKinetic which later was acquired by Sony. Following a licensing agreement with the latter, Melexis turned this sensor into a single-chip solution and combines it with a matching SDK. Target applications include in-car and exterior monitoring.

The MLX75027 is a system-on-chip solution, providing VGA (640 x 480 pixel) resolution image sensing and processing in a single BGA package, offering two times higher performance than the earlier version.

As the industry continues towards semi-autonomous vehicles, in-car monitoring is being used to monitor the driver and other occupants of a vehicle, both as a user interface and a safety feature. The introduction of the MLX75027 reinforces Melexis’ leadership in this application space, with the industry’s first single-chip VGA ToF sensor.

The device uses a modulated light source and optical time-of-flight sensing to create a three-dimensional image of the cabin, allowing it to monitor people and objects, as well detect gestures. It can also be used to detect free space and obstacles outside of the vehicle, such as pedestrians, for collision warning and navigation applications. The MLX75027 is able to operate in an ambient temperature of -40 to +105°C.
