Time-of-flight sensor has QVGA resolution
With the MLX75026, Melexis offers a 3D time-of-flight camera sensor that doubles the resolution over its existing products – at half the size.

The MLX75026 delivers over twice the performances of the previous generation of ToF sensors in terms of quantum efficiency and distance accuracy. The device is software-compatible with the vendor’s existing MLX75027 Gen 3 VGA ToF sensor, facilitating migration between VGA and QVGA resolutions. The new sensor is also half the size and requires only 30% of the computing power needed by the MLX75027 VGA ToF sensor.
A fully integrated solution, the MLX75026 is said to be ideal for automotive use cases like driver monitoring systems (DMS), hand movement and robust gesture recognition (HMI) and for in-cabin monitoring systems (IMS). It delivers intrinsic robustness with respect to scenes with low contrast and strong sunlight, which are usually a severe challenge for conventional 2D image sensors. This makes the MLX75026 ideal for applications where reliability and availability of data is important. The device is also targeting other markets and applications for which QVGA resolution is adequate, including robust people counting and object/obstacle detection. 
MLX75026 has QVGA (320x240 pixels) resolution with a 1/4 inch optical format and supports both 850 nm and 940 nm illumination. The IC is configurable over an I2C interface and provides CSI-2 serial data output. The small form factor, simple power supply requirements, very low power consumption and low number of external components on the PCB allow the design of compact and cost-effective ToF cameras.

Samples of the MLX75026 are available now, and the evaluation kit in November 2020.
