VCNL3036 www.vishay.com Vishay Semiconductors High Resolution Digital Biosensor for Wearable Applications 2 With I C Interface FEATURES Package type: surface-mount Dimensions (L x W x H in mm): 4.0 x 2.36 x 0.75 Integrated modules: biosensor (BIO), photo diode (PD), and signal conditioning IC Temperature compensation: -25 C to +85 C 2 Low power consumption IC (SMBus compatible) interface 2 Output type: I C bus Operation voltage: 2.5 V to 3.6 V V 1 8 SDA DD Floor life: 168 h, MSL 3, according to J-STD-020 SCL 2 7 INT Material categorization: for definitions of compliance GND 3 6 LED1 please see www.vishay.com/doc 99912 LED3 4 5 LED2 OPTICAL BIOSENSORS FUNCTION Broader sensitivity photodiode allows to also work with green and red LED DESCRIPTION Programmable LED sink current VCNL3036 integrates a biosensor (BIO), a mux, and a driver Intelligent cancellation to reduce cross talk phenomenon for up to 3 external IREDs / LEDs into one small package. It incorporates photodiodes, amplifiers, and analog to digital Smart persistence scheme to reduce response time converting circuits into a single chip by CMOS process. BIO Selectable for 12-bit / 16-bit BIO output data programmable interrupt features of individual high and low thresholds offers the best utilization of resource and power INTERRUPT saving on the microcontroller. Programmable interrupt function for BIO with upper and The biosensor features an intelligent cancellation scheme, lower thresholds so that cross talk phenomenon is eliminated effectively. To Adjustable persistence to prevent false triggers accelerate the BIO response time, smart persistence prevents the misjudgment of proximity sensing but also APPLICATIONS keeps a fast response time. Active force mode, one tim e Handheld device trigger by one instruction, is another good approach for more design flexibility to fulfill different kinds of applications Wearable devices with more power saving. Consumer device VCNL3036 provides an excellent temperature Fitness and medical monitoring applications compensation capability for keeping output stable under various temperature configurations. BIO functions are easily 2 operated via the simple command format of I C (SMBu s compatible) interface protocol. Operating voltage ranges from 2.5 V to 3.6 V. VCNL3036 is packaged in a lead (Pb)-free 8-pin QFN package, which offers the best market-proven reliability quality.
