MAX25405 IR Gesture Sensor with Lens for Automotive Applications General Description Benefits and Features The MAX25405 is a low-cost, data-acquisition system for Low-Cost, Flexible Gesture-Sensing Solution for gesture and proximity sensing. Detection distance is im- Automotive Applications proved by integrating a complete optical system consisting Low-Power, Low-Cost External CPU Processes of lens, aperture, visible light filter, and a 6x10 photode- Sensor Output tector array. The MAX25405 recognizes the following in- Supports Swipe, Rotation, and Proximity Gestures dependent gestures: Highly Integrated Integrated Lens, Aperture, and Filter Hand swipe gestures (left, right, up, down, wave) 60-Pixel IR Photodiode Array Air click Integrated LED Driver Flicks 2 400kHz I C and 6MHz SPI Serial Interfaces Finger and hand rotation (clockwise and counter clockwise) Operates in 120k Lux Ambient Light Multizone proximity detection AEC-Q100 Qualified Linger to click -40C to +85C Operation MSL1 The proximity, hand detection, and gesture recognition functions of the MAX25405 operate by detecting the light Ultra-Low-Power Operation reflected from the controlled IR-LED light source with an 1mA at 3.3V integrated 6x10-element optical sensor array. The Compact 4mm x 4mm x 1.35mm, 20-Pin, Side- MAX25405 can detect these gestures even when exposed Wettable QFN Package to bright ambient light. A low-power, low-cost CPU, such as the MAX32630, is required to process the data from the Ordering Information appears at the end of the data sheet. sensor. This discrete light source is created externally with one or more FETs driven directly from the MA25405. The light sources PWM duty cycle is programmable from 1/16 to 16/16. The LEDs are pulsed on one or more times in a programmable sequence repeated for every sample. For flexibility, the MAX25405 supports two different serial 2 communication protocols: I C (400kHz) and SPI (6MHz). The MAX25405 is available in a 4mm x 4mm, 20-pin, opti- cal QFN package.
