DESCRIPTION

VCNL4030X01 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 for excellent

sensing capabilities with sufficient selections to fulfill most

applications whether dark or high transparency lens design.

Both ALS and PS offer a programmable interrupt with

individual high and low thresholds offers the power savings

on the microcontroller.

The proximity sensor features an intelligent cancellation

scheme, so that cross talk is eliminated effectively. The

proximity’s smart persistence feature prevents the

misjudgment of proximity sensing with a fast response time.

Active force mode, one time trigger by one instruction, offers

more design flexibility to fulfill different kinds of applications

with more power savings.

The adoption of patented FiltronTM technology achieves the

closest ambient light spectral sensitivity to real human eye

responses and offers the best background light cancellation

capability (including sunlight) without utilizing the

microcontrollers’ resources. VCNL4030X01 provides an

excellent temperature compensation capability for keeping

the output stable over temperature. ALS and PS functions

are easily operated via the simple command format of I2C

(SMBus compatible) interface protocol. Operating voltage

ranges from 2.5 V to 3.6 V. VCNL4030X01 is packaged in a

lead-free 8-pin QFN package, which offers the best

market-proven reliability quality
