Fully Integrated Proximity and Ambient Light Sensor with
Infrared Emitter, I
2
C Interface, and Interrupt Function
DESCRIPTION
The VCNL4020 is a fully integrated proximity and ambient
light 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.
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
