General Description The MLX75030 Universal ActiveLight Sensor Interface has been designed to allow easy and robust dual-channel optical reflection and dual channel ambient light measurement. Therefore it is ideally suited for the design of responsive human-machine interfaces (HMI) that require proximity or gesture detection in environments subject to wide background light level variations, possibly in combination with display dimming. The MLX75030 IC consists of two optical sensor interface parts. Part one is optimized for active light measurements and is designed to control up to 2 external LEDs and to sense modulated light current from up to 2 external photodiodes on independent channels A and B. The ActiveLight detection is virtually independent from background light by means of integrated hardware-level ambient light suppression. Part two consists of two logarithmic current sensors C and D, which measure the photocurrent of externally connected photodiodes. Simple and programmable operation is ensured by internal control logic, configurable user registers and SPI communication. 2.
