THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENTARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT Integrated Proximity and Ambient Light Sensor WithI2C Interface and Interrupt Function for Gesture ApplicationsDESIGN SUPPORT TOOLS AVAILABLEDESCRIPTIONVCNL4035X01 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.

2 Both ALS and PS programmable interrupt features of individual high and low thresholds offers the best utilization of resource and power saving on 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 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.

3 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 V to V. VCNL4035X01 is packaged in a lead-free 8-pin QFN package, which offers the best market-proven reliability Package type: surface-mount Dimensions (L x W x H in mm): x x AEC-Q101 qualified Integrated modules: Ambient Light sensor (ALS), Proximity sensor (PS), and signal conditioning ICL Operates ALS and PS in parallel structure FiltronTM technology adoption for robust background Light cancellation Temperature compensation: -40 C to +105 C Low power consumption I2C (SMBus compatible) interface Output type: I2C bus (ALS / PS) Operation voltage: V to V Floor life: 168 h, MSL 3, according to J-STD-020 Material categorization.
