Vishay – AEC-Q101-Qualified VCNL4020X01 Proximity and Ambient Light Optical Sensor

The Optoelectronics group of Vishay Intertechnology, Inc. (NYSE: VSH) announces a new AEC-Q101-qualified, fully integrated proximity and ambient light optical sensor with an industry-high operating temperature range to +105 ºC. The VCNL4020X01 combines an IR emitter, a photo-pin-diode for proximity, an ambient light detector, a signal processing IC, and a 16-bit ADC in one small 4.9 mm x 2.3 mm x 0.8 mm rectangular lead-less (LLP) package. The 3-in-1 sensor features an interrupt function, supports I2C bus communication interface, and greatly simplifies window and sensor placement in a wide variety of automotive, consumer, and industrial applications.
