NCV76124 Description
Rain and Light Sensor Interface with SPI NCV76124 The NCV76124 is an interface chip for rain and light detection in automotive applications. It measures 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.
