MAX25405EQP/VY+

MAX25405EQP/VY+ is an IR gesture sensor with a lens for automotive applications. Detection distance is improved by integrating a complete optical system consisting of a lens, aperture, visible light filter, and a 6x10 photodetector array. The proximity, hand detection, and gesture recognition functions of the device operate by detecting the light reflected from the controlled IR-LED light source with an integrated 6x10-element optical sensor array. It can detect these gestures even when exposed to bright ambient light. A low-power, low-cost CPU, such as the MAX32630, is required to process the data from the sensor. This discrete light source is created externally with one or more FETs driven directly from the MAX25405. It is used in applications such as central information display control, rear-seat entertainment systems, door, moon roof, and trunk control, mechanical switch replacement, and occupant detection.
