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
2
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
• Package type: surface mount
• Dimensions (L x W x H in mm): 4.90 x 2.40 x 0.83
• Integrated infrared emitter, proximity sensor,
and signal conditioning IC
• Interrupt function
• Supply voltage range V
DD
: 2.5 V to 3.6 V
• Supply voltage range IR anode: 2.5 V to 5 V
• Communication via I

C Bus H-level range: 1.7 V to 5 V
• Floor life: 72 h, MSL 4, acc. J-STD-020
• Low stand by current consumption: 1.5 μA
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
PROXIMITY FUNCTION
• Built-in infrared emitter and photo-pin-diode for proximity
function
• 16 bit effective resolution for proximity detection range
ensures excellent cross talk immunity
• Programmable LED drive current from 10 mA to 200 mA in
10 mA steps
• Excellent ambient light suppression by signal modulation
• Proximity distance up to 200 mm
