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.
