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.
