DESCRIPTION

VCNL4035X01 integrates a proximity sensor (PS),

ambient light sensor (ALS), a muxx, 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. The

16-bit high resolution ALS offers excellent sensing

capabilities with sufficient selections to fulfill most

applications whether dark or high transparency lens design.

Both ALS and PS programmable interrupt features of

individual high and low thresholds offers the best utilization

of resource and power saving on the microcontroller.

The proximity sensor features an intelligent cancellation

scheme, so that cross talk phenomenon is eliminated

effectively. To accelerate the PS 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.

The adoption of patented FiltronTM technology achieves the

closest ambient light spectral sensitivity to real human eye

responses and offers the best background light cancellation

capability (including sunlight) without utilizing the

microcontrollers’ resources. VCNL4035X01 provides an

excellent temperature compensation capability for keeping

output stable under various temperature configurations.

ALS and PS 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.

VCNL4035X01 is packaged in a lead-free 8-pin QFN

package, which offers the best market-proven reliability

quality
