DESCRIPTION

PROXIMITY FUNCTION

The VCNL4020X01 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 I²C communication interface. It features an

interrupt 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

APPLICATIONS

• Excellent ambient light suppression by signal modulation

• Proximity distance up to 200 mm

• Proximity sensor for:

- Mobile devices (e.g. smart phones, touch phones,

PDAs, GPS) for touch screen locking, power saving etc.

AMBIENT LIGHT FUNCTION

- Automotive for presence detection

• Built-in ambient light photo-pin-diode with close-to-

human-eye sensitivity

• Integrated ambient light function for display / keypad

contrast control and dimming of mobile devices

• 16 bit dynamic range from 0.25 lx to 16 klx

• 100 Hz and 120 Hz flicker noise rejection

• Rear view mirror dimming in automotive

• Proximity / optical switch for consumer, computing,

automotive and industrial devices, and displays (like

notebooks, tablet PCs, and automotive touch panels)

• Dimming control for consumer, computing, industrial, and

automotive displays
