Vishay VCNL4030X01 automotive grade proximity and ambient light sensor

VCNL4030X01 integrates a proximity sensor, ambient light sensor, and a high power IRED into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process. The 16-bit high resolution ALS for excellent sensing capabilities with sufficient selections to fulfill most applications whether dark or high transparency lens design. Both ALS and PS offer a programmable interrupt to save power on the microcontroller. The proximity sensor features an intelligent cancellation scheme, so that cross talk is eliminated effectively.
