VCNL4035X01 - Fully Integrated Proximity and Ambient Light Sensor

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.

• 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 d.
