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

⢠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
