V I S H AY I N T E R T E C H N O L O G Y, I N C . OPTOELECTRONICS VCNL Por tfolio Fully Integrated Proximity and Ambient Light Sensors The VCNL4010, VCNL4020, and VCNL4020X01 are fully integrated proximity and ambient light sensors. Fully integrated means they contain the infrared emitter and photo detector for proximity, an ambient light sensor, a signal processing IC, and I2C communication interface. The VCNL3020 supports only proximity sensing; it does not contain an ambient light sensor. With full 16-bit resolution for both the proximity and ambient features, user-defined interrupt levels, and multiple packaging options, the VCNL portfolio will fulfill your requirements. FEATURES • Proximity function –– 16-bit resolution –– Excellent crosstalk immunity –– Programmable LED drive current from 10 mA to 200 mA in 10 mA steps –– Programmable measurement rate from 1 Hz to 250 Hz –– Proximity distance up to 20 cm (8 in.) –– Includes driver for an external emitter for increased range • Ambient light function –– Built-in ambient light PIN photodiode with close to human eye sensitivity characteristic –– 16-bit dynamic range for ambient light detection from 0.25 lx to 16 klx –– 100 Hz and 120 Hz flicker noise rejection RESOURCES • • • • Datasheets: VCNL4010, VCNL4020, VCNL3020, VCNL4020X01 VCNL product family: http://www.vishay.com/optoelectronics/moreinfo/vcnlfamily For technical questions, contact [email protected] Sales contacts: http://www.vishay.com/doc?99914 One of the World’s Largest Manufacturers of Discrete Semiconductors and Passive Components PRODUCT SHEET 1/2 VMN-PT0251-1405 THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.

When proximity is active, the current consumption is a function of the emitter current and the measurements per second. A current calculator is available at http://www.vishay.com/optoelectronics/opto-sensors-calculator/. EVALUATION KITS An evaluation kit is available for each of the sensors. Contact any catalog distributor or a local Vishay sales representative to purchase the Sensor Starter Kit and contact [email protected] for kits with the VCNL4010, VCNL4020X01, or VCNL3020.
