DESCRIPTION
VCNL4000 is a fully integrated proximity and ambient light
digital 16 bit resolution sensor in a miniature lead less
package (LLP) for surface mounting. It includes a signal
processing IC and supports an easy to use I2C bus
communication interface.
APPLICATIONS
• Proximity sensor for mobile devices (e.g. smart phones,
touch phones, PDA, GPS) for touch screen locking, power
saving, etc.
• Integrated ambient light function for display/keypad
contrast control and dimming of mobile devices
• Proximity/optical switch for consumer, computing and
industrial devices and displays
• Dimming control for consumer, computing and industrial
displays
FEATURES
• Package type: surface mount
• Dimensions (L x W x H in mm): 3.95 x 3.95 x 0.75
• Integrated module with ambient light sensor,
proximity sensor and signal conditioning IC
• Supply voltage range VDD: 2.5 V to 3.6 V
• Supply voltage range IR anode: 2.5 V to 5 V
• Communication via I2C interface
• I2C 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
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
PROXIMITY FUNCTION
• Built in infrared LED 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
AMBIENT LIGHT FUNCTION
• Built in ambient light photo-pin-diode 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
