Compared to ToF camera-based systems
10% less cost and 75% smaller size
Detects 9 motions including screen transitions and rotations


Most motion detection systems installed in vehicles are based on expensive and complex time-of-flight (ToF) cameras, so related companies are looking for alternatives.

Maxim Integrated Korea announced on the 23rd that it has launched the 'MAX25205' automotive motion sensor that implements motion detection control function at low cost and small size.

Replacing buttons or touchscreens for answering phone calls, operating side mirrors, operating the air conditioning, opening the trunk or sunroof, and turning on interior lights with motion and proximity-sensing controls can improve driver safety.

The MAX25205, which can implement motion detection functions such as screen switching and rotation, consists of a 60-photodiode array, an LED driver, and an LDO regulator. It is up to 10% cheaper than ToF camera-based solutions and 75% smaller with a 4x4mm chip size. It is compatible with small MCUs, so there is no need to use MPUs, software development, or maintenance programs.

The solution, which recognizes nine gestures including low-latency screen flip, rotation, Airlink, and 3x2 proximity detection with just a single chip, is suitable for automotive as well as consumer and industrial products such as smart home hubs and temperature sensors.
