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 Filtron
TM
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 I
2
C
(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.
