DESCRIPTION

VCNL3036 integrates a biosensor (BIO), a mux, and a driver

for up to 3 external IREDs / LEDs into one small package. It

incorporates photodiodes, amplifiers, and analog to digital

converting circuits into a single chip by CMOS process. BIO

programmable interrupt features of individual high and low

thresholds offers the best utilization of resource and power

saving on the microcontroller.

The biosensor features an intelligent cancellation scheme,

so that cross talk phenomenon is eliminated effectively. To

accelerate the BIO response time, smart persistence

prevents the misjudgment of proximity sensing but also

keeps a fast response time. Active force mode, one time

trigger by one instruction, is another good approach for

more design flexibility to fulfill different kinds of applications

with more power saving.

VCNL3036 provides an excellent temperature

compensation capability for keeping output stable under

various temperature configurations. BIO functions are easily

operated via the simple command format of I2C (SMBus

compatible) interface protocol. Operating voltage

ranges from 2.5 V to 3.6 V. VCNL3036 is packaged in a

lead (Pb)-free 8-pin QFN package, which offers the best

market-proven reliability quality.
