Automotive Grade Proximity and Ambient Light Sensor Provides Four Different Slave Address Options

The Optoelectronics group of Vishay Intertechnology, Inc. introduced a new fully integrated Automotive Grade proximity and ambient light sensor with four different slave address options. Featuring Filtron™ technology, the Vishay Semiconductors VCNL4030X01 combines photo detectors for proximity and ambient light, a signal conditioning IC, a 16-bit ADC, and a high power IRED in one compact 4 mm by 2.36 mm by 0.75 mm surface-mount package. The AEC-Q101 qualified sensor features an interrupt function and supports I²C bus communication interface for mobile devices and smart home, industrial, and automotive applications.

The device can be implemented to provide proximity sensing for touchscreen locking in smartphones and tablets to save power; presence detection for display activation in notebooks, automobiles, and consumer and industrial devices; ambient light sensing for dimming control in displays, keypads, and rear-view mirrors; and collision avoidance in toys and robots. All the circuitry needed for these applications is included in one compact package to save PCB space, while its four slave address options provide greater design flexibility in applications requiring more than one sensor (more info).
