DESCRIPTION

· The MLX75031 is an Optical Gesture & Proximity Sensing IC that controls up to 2 independent Active Light measurement channels, each consisting of LEDs and photodiodes.

· It features integrated DC light suppression for high tolerance to background light and includes two ambient light channels.

· The IC supports internal control logic, configurable user registers, and SPI communication for programmable operation.

· Additional features include a watchdog timer, on-board temperature sensor, and self-diagnostics for robust design.

· It enables proximity and ambient light detection, and supports gesture recognition through software algorithms.

FEATURES

· Two independent Active Light measurement channels for proximity sensing and gesture recognition.

· Integrated DC light cancellation and two logarithmic ambient light channels with different sensitivities.

· Minimal external components required, with stand-by and sleep modes for low power consumption.

· Integrated LED drivers, battery voltage monitor, and temperature sensing circuitry.

· High-resolution 16-bit ADC, temperature sensor, and watchdog timer included.

· Easy digital communication via SPI, high input capacitance tolerant terminals, and high safety design with diagnostic functions.
