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.
