Vishay's VCNL4035X01 integrates a proximity sensor (PS), ambient light sensor (ALS), a mux, and a driver for up to three 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 the ALS and PS have programmable interrupt features of individual high and low thresholds, which offer 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 Filtron™ 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. It offers operating voltage ranges from 2.5 V to 3.6 V.

VCNL4035X01 is packaged in a lead-free 8-pin molding package, which offers the best market-proven reliability quality.
