Fully Integrated Proximity Sensor With Infrared Emitter,
I
2
C Interface, and Interrupt Function
DESCRIPTION
The VCNL3020 is a fully integrated proximity sensor. Fully
integrated means that the infrared emitter is included in the
package. It has 16 bit resolution. It includes a signal
processing IC and features standard I

C communication
interface. It features an interrupt function.
APPLICATIONS
• Proximity sensor for mobile devices (e.g. smart phones,
touch phones, PDA, GPS) for touch screen locking, power
saving, etc.
• Proximity / optical switch for consumer, computing and
industrial devices and displays
FEATURES
