Pointe Claire, Quebec – Future Electronics, a global leading distributor of electronic components, promotes Vishay's VCNL4040 Series of proximity and ambient light sensors.
The VCNL4040 Series integrates a proximity sensor (PS), ambient light sensor (ALS), and a high power IRED 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. High and low interrupt thresholds can be programmed for both ALS and PS, allowing the component to use a minimal amount of the microcontrollers' resources.
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 while also keeping a fast response time. In active force mode, a single measurement can be requested, allowing another good approach for more design flexibility to fulfill different kinds of applications with more power savings.
The patented Filtron™ technology achieves ambient light spectral sensitivity closest to real human eye response and offers the best background light cancellation capability (including sunlight) without utilizing the microcontrollers' resources. The VCNL4040 Series provides an excellent temperature compensation capability for keeping output stable under various temperature configurations. ALS and PS functions are easily set via the simple command format of I2C (SMBus compatible) interface protocol.
With operating voltage ranges from 2.5 V to 3.6 V, the VCNL4040 Series is offered in a lead-free 8-pin molding package, providing the best market-proven reliability quality.
Typical applications include handheld devices, notebooks, tablet PCs, consumer devices, and industrial applications.
