Rain-light sensor interface IC

The MLX75308 is a sensor interface that is dedicated to rain and light measurement, with two independent linear rain measurement channels and three logarithmic ambient channels.

The device measures rain and sun signals, interfacing to an MCU via SPI.

Offering a superior level of performance and feature size over competing solutions, our MLX75308 is a highly versatile system component, with a large dynamic input range and output range.

The output range can support LED currents up to 1A. This large dynamic range facilitates the use of a wide variety of photodiodes and windscreen types, suiting the part to automotive customers that desire a ‘one system fits all’ solution.
