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
