MAX25405 next-generation optical sensor recognizes a variety of gestures in a quarter of the size and at 10x lower cost than camera-based time-of-flight systems in next-generation automotive, industrial and consumer applications
SAN JOSE, Calif., June 28, 2021 /PRNewswire/ -- Maxim Integrated Products, Inc. (NASDAQ: MXIM) today introduced the next generation of its infrared-based dynamic optical sensor, able to sense a broader range of gestures at extended distances. The MAX25405 detects a wider proximity of movement and doubles the sensing range to 40cm when compared to earlier generations, all in a quarter of the size and at 10x lower cost than time-of-flight (ToF) camera-based systems in automotive, industrial and consumer applications. These enhancements offer an alternative to voice communications, enabling drivers to focus on the road.

Along with integrated optics and a 6 x 10 infrared sensor array, the next-generation MAX25405 now includes a glass lens which increases sensitivity and improves the signal-to-noise ratio. The improved performance doubles the proximity and distance of sensing applications to beyond the driver, offering gesture-sensing entertainment displays to the co-driver and rear seat passengers, for example. The MAX25405 features a high level of integration compared to competitive ToF solutions that require three chips and a complicated microprocessor. The MAX25405's small 20-pin, 4mm x 4mm x 1.35mm quad flat no-lead (QFN) package together with four discrete LEDs measures up to 75 percent smaller than ToF camera-based solutions.
Wide sensing range: The MAX25405 senses a wider proximity of movement and doubles the sensing range from 20cm to 40cm when compared to earlier infrared generations.
Lowest cost and smallest size: The MAX25405 senses swipe, rotation and other important gestures at a lower cost than ToF cameras. High integration results in a total solution size that is significantly smaller than ToF camera solutions.
Versatile: The MAX25405 recognizes nine gestures, including swipe, rotation, air-click, linger to click and 3 x 2 proximity zones with minimal lag time. This cost-effective single chip makes gesture-sensing affordable for multi-range automotive, consumer and industrial applications, including touch-free smart home hubs, thermostats and many more.
"Maxim Integrated's MAX25405 recognizes the most dynamic gestures at the lowest cost, allowing automakers to avoid the prohibitive cost of time-of-flight cameras and to help keep drivers' eyes on the road," said Szu-Kang Hsien, director for the Automotive Business Unit at Maxim Integrated. "The affordable gesture sensing feature adds value to low- and mid-range cars, while offering passengers the luxury of touch-free gesture control."
