The NCV76124 is an interface chip for rain and light detection in automotive applications. It measures external photodiode currents that represent rain and light signals, and transfers the converted signals to a master microcontroller on request via the SPI interface. The rain measurement data can be used to control the rain wipers. The light intensity signals can be used for e.g. brightness control of displays, the headlamp control and others. Thanks to the SPI programmability, one single hardware configuration can support various applications.
