Vishay VNCL4035X01

VCNL4035X01 is a fully integrated proximity sensor and ambient light sensor with I²C interface and interrupt function for gesture applications. It incorporates photodiodes, amplifiers and analog to digital converting circuits into a single chip.

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.

VNCL4035X01 is fully automotive qualified (AEC-Q101).
