MAX25405 Infrared-based Dynamic Optical Sensor from Maxim Integrated

The next generation MAX25405 infrared-based dynamic optical sensor from Maxim Integrated detects wider proximity of movement and doubles the sensing range to 40cm besides offering 10x lower cost than time-of-flight (ToF) camera-based systems in automotive, industrial, and consumer applications. This new sensor with integrated optics and a 6 x 10 infrared sensor array comprises of a glass lens which increases sensitivity and improves the signal-to-noise ratio.

The improved performance of the MAX25405 infrared-based dynamic optical sensor doubles the proximity and distance of sensing applications 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% smaller than ToF camera-based solutions.

Key Advantages of MAX25405 Sensor

  • Wide sensing range: The MAX25405 senses 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.

The MAX25405 power management IC and associated MAX25405EVKIT# evaluation kit are available from Maxim Integrated and authorized distributors. The pricing details will be available upon request.
