DESCRIPTION

VCNL36825T integrates a proximity sensor (PS), and a

VCSEL 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 offers the best

utilization of resource and power saving on the

microcontroller.
