VCNL36821S integrates a proximity sensor (PS), and a IRED into one small package

Vishay VCNL36821S product picture

VCNL36821S integrates a proximity sensor (PS), and a IRED into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process. PS programmable interrupt features of individual high and low thresholds offer the best utilization of resource and power saving on the microcontroller.
