Fully Integrated Proximity and Ambient Light Sensor with

Infrared Emitter, I²C Interface, and Interrupt Function

FEATURES

• Package type: surface mount

• Dimensions (L x W x H in mm): 4.0 x 2.0 x 1.1

• Integrated modules: infrared emitter (IRED),

ambient light sensor (ALS), proximity sensor

(PS), and signal conditioning IC

• Operates ALS and PS in parallel structure

• Filtron^TMtechnology adoption for robust

background light cancellation

• Temperature compensation: -40 °C to +85 °C

• Low power consumption I²C (SMBus compatible)

interface

DESCRIPTION

• Floor life: 168 h, MSL 3, according to J-STD-020

• Output type: I²C bus (ALS / PS)

VCNL4040 integrates a proximity sensor (PS), ambient

light sensor (ALS), and a high power IRED into one small

package. It incorporates photodiodes, amplifiers, and

analog to digital converting circuits into a single chip by

CMOS process. The 16-bit high resolution ALS offers

excellent sensing capabilities with sufficient selections to

fulfill most applications whether dark or high transparency

lens design. High and low interrupt thresholds can be

programmed for both ALS and PS, allowing the component

to use a minimal amount of the microcontrollers resources.

• Operation voltage: 2.5 V to 3.6 V

• Material categorization: for definitions of compliance

please see www.vishay.com/doc?99912

PROXIMITY FUNCTION

• Immunity to red glow (940 nm IRED)

• Programmable IRED sink current

The proximity sensor features an intelligent cancellation

scheme, so that cross talk phenomenon is eliminated

effectively. To accelerate the PS response time, smart

persistence prevents the misjudgment of proximity sensing

but also keeps a fast response time. In active force mode, a

single measurement can be requested, allowing another

good approach for more design flexibility to fulfill different

kinds of applications with more power saving.

The patented Filtron^TMtechnology achieves ambient light

spectral sensitivity closest to real human eye response and

offers the best background light cancellation capability

(including sunlight) without utilizing the microcontrollers’

resources. VCNL4040 provides an excellent temperature

compensation capability for keeping output stable under

various temperature configurations. ALS and PS functions

are easily set via the simple command format of I²C (SMBus

compatible) interface protocol. Operating voltage ranges

from 2.5 V to 3.6 V. VCNL4040 is packaged in a lead-free

8-pin molding package, which offers the best

market-proven reliability quality.

• Intelligent cancellation to reduce cross talk phenomenon

• Smart persistence scheme to reduce PS response time

• Selectable for 12- / 16-bit PS output data

AMBIENT LIGHT FUNCTION

• High accuracy of ALS 10 ꢀ

• Fluorescent light flicker immunity

• Spectrum close to real human eye responses

• Selectable maximum detection range (819 / 1638 / 3277 /

6553) lux with highest sensitivity 0.0125 lux/step

INTERRUPT

• Programmable interrupt function for ALS and PS with

upper and lower thresholds

• Adjustable persistence to prevent false triggers for ALS

and PS

APPLICATIONS

• Handheld device

• Notebook, tablet PC

• Consumer device

• Industrial application
