MAX25205EQP/VY+

MAX25205EQP/VY+ is a gesture sensor for automotive application. It is a low-cost data-acquisition system for gesture and proximity sensing. It recognizes the following independent gestures that is hand swipe gestures (left, right, up, and down), finger and hand rotation, proximity detection. The proximity, hand detection, and gesture recognition functions of the MAX25205 operate by detecting the light reflected from the controlled IR-LED light source with an integrated 6x10-element optical sensor array. The MAX25205 can detect these gestures even when exposed to bright ambient light. This discrete light source is created externally with one or more FETs driven directly from the MA25205. The light source’s PWM duty cycle is programmable from 1/16 to 16/16. Application includes central information display control, rear-seat entertainment systems, door, moon roof, and trunk control, mechanical switch replacement, occupant detection.
