Vishay Semiconductors VCNL Proximity & Ambient Light Sensors

Vishay Semiconductors VCNL Proximity & Ambient Light Sensors

Vishay Semiconductors VCNL Proximity & Ambient Light Sensors are optical sensors each combining an IR emitter, PIN photodiode, ambient light detector, signal processing IC, with 16-bit resolution, and an I²C interface. These features are integrated to greatly simplify window and sensor placement, PCB layout, and communication functions in a wide variety of consumer and industrial applications. The combination of the proximity sensor, ambient light sensor, and infrared emitter into a single component not only simplifies the design-in process by making a mechanical barrier unnecessary, but virtually eliminates optical crosstalk in smart phones.

Vishay Semiconductors VCNL4020 Fully Integrated Proximity & Ambient Light Sensor


Vishay Semiconductors VCNL4020 Fully Integrated Proximity & Ambient Light Sensor 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 4.8 x 2.3 x 0.8mm rectangular leadless (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 consumer and industrial applications. It also features the industry's lowest height of 0.8mm, and a 16 bit resolution.

For mobile devices such as smart phones, touch phones, PDAs, GPS units, and digital cameras, the new VCNL4020 saves power as a proximity sensor by turning off the display backlight when close to the user, while using its integrated ambient light function for display/keypad adaptive brightness control. Containing all the circuitry needed for these applications in one device, the VCNL4020 eliminates the need for additional light barriers and optical alignment of the IR emitter and photo diode.
