DESCRIPTION

VCNL4100 integrates a high sensitivity long distance

proximity sensor (PS), ambient light sensor (ALS), and

940 nm IRED into one small package. It incorporates

photodiodes, amplifiers, and analog to digital converting

circuits into a single chip using a CMOS process. The 16-bit

high resolution ALS offers excellent sensing capabilities

with sufficient selections to fulfill most applications whether

a dark or high transparency lens design. VCNL4100 offers

individual programmable high and low threshold interrupt

features for the best utilization of resources and power

saving on the microcontroller. For the 8-bit proximity

sensing function, VCNL4100 has a built-in intelligent

cancellation scheme that eliminates background light

issues. The persistence feature prevents false judgment of

proximity sensing due to ambient light noise.

the closest ambient light spectral sensitivity to real human

eye responses. VCNL4100 provides excellent temperature

compensation capability for keeping the output stable under

changing temperature. ALS and PS functions are easily

compatible) interface protocol. Operating voltage ranges

from 2.5 V to 3.6 V.
