Automotive-grade sensor supports both proximity and ambient light detection

The optoelectronics group of Vishay Intertechnology, Inc. has unveiled a fully integrated automotive-grade proximity and ambient light sensor that comes complete with four different slave address options. The new Vishay Semiconductors VCNL4030X01 features Filtron technology, combining photo detectors for proximity and ambient light, a signal conditioning IC, a 16-bit ADC, and a high-power IRED in a 4 × 2.36 × 0.75-mm surface-mount package.

The device can be implemented in several ways: as proximity sensing for touch-screen locking in smartphones and tablets to save power; presence detection for display activation in notebooks, consumer and industrial devices, and automobiles; and ambient light sensing for dimming control in keypads, displays, and rearview mirrors as well as collision avoidance in toys and robots. The packages come complete with all necessary circuitry for these applications to save board space while the four slave address options provide design flexibility in applications that require more than one sensor, said Vishay.

The AEC-Q101–qualified sensor also offers a programmable interrupt function that is used to set high and low thresholds, reducing total power consumption within any application. You can program the function to trigger both the ambient light and proximity sensor. It also supports an I²C bus communication interface for automotive, industrial, mobile device, and smart home applications.

Thanks to the Filtron technology, the device offers ambient light spectral sensitivity close to that of the human eye and excellent background light cancellation capabilities, according to Vishay.

  2. “It's really quite amazing what sorts of things can be detected by sensors these days. I would reckon that people are going to want to manage the amount of control that they have over such detection systems though. I'm not sure how relevant this is, but I'
