DESCRIPTION
VCNL4035X01 integrates a proximity sensor (PS),
ambient light sensor (ALS), a muxx, and a driver for up
to 3 external IREDs / LEDs 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.
Both ALS and PS programmable interrupt features of
individual high and low thresholds offers the best utilization
of resource and power saving on the microcontroller.
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. Active force mode, one
time trigger by one instruction, is another good approach for
more design flexibility to fulfill different kinds of applications
with more power saving.
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. VCNL4035X01 provides an
excellent temperature compensation capability for keeping
output stable under various temperature configurations.
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.
VCNL4035X01 is packaged in a lead-free 8-pin QFN
package, which offers the best market-proven reliability
quality.

Adjustable Sampling Time
VCNL4035X01’s embedded LED driver drives up to 3 external IREDs by a pulsed duty cycle. The IRED on / off duty ratio is
programmable by I2C command at register: PS_Duty which is related to the current consumption and PS response time. The
higher the duty ratio adopted, the faster response time achieved with higher power consumption. For example, PS_Duty =
1/320, peak IRED current = 100 mA, averaged current consumption is 100 mA/320 = 0.3125 mA.
Initialization
VCNL4035X01 includes default values for each register. As long as power is on, it is ready to be controlled by host via I2C bus.
