Vishay VCNL4030X01 Proximity & Ambient Light Sensors

Vishay VCNL4030X01 Proximity and Ambient Light Sensors integrate a proximity sensor (PS), ambient light sensor (ALS), and a high power IRED into one small package. The VCNL4030X01 uses a CMOS process incorporating 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, ideal for most applications whether a dark or high transparency lens design is required. The ALS and PS both provide a programmable interrupt with individual high and low thresholds allowing power savings on the microcontroller. The proximity sensor features smart persistence, which prevents the misjudgment of proximity sensing with a fast response time. The proximity sensor also offers an intelligent cancellation scheme eliminating crosstalk effectively.

The VCNL4030X01 further presents an Active Force Mode, that provides more design flexibility to fulfill different kinds of applications with more power savings. The VCNL4030X01 utilizes Filtron™ technology, achieving the closest ambient light spectral sensitivity to real human eye responses. This Filtron™ technology gives the best background light cancellation capability (including sunlight) without using the microcontrollers’ resources. The Vishay VCNL4030X01 Proximity and Ambient Light Sensors provide an excellent temperature compensation capability, thus keeping the output stable over temperature. ALS and PS functions are easily operated via the simple command format of the I²C (SMBus compatible) interface protocol.
