333 3 VCNL3040 www.vishay.com Vishay Semiconductors 2 Proximity Sensor With Interrupt, IRED, and I C Interface FEATURES Package type: surface-mount Dimensions (L x W x H in mm): 4.0 x 2.0 x 1.1 Integrated modules: infrared emitter (IRED), proximity sensor (PS), and signal conditioning IC 2 Low power consumption IC (SMBus compatible) interface Floor life: 168 h, MSL 3, according to J-STD-020 2 Output type: I C bus (PS) ADDITIONAL RESOURCES Operation voltage: 2.5 V to 3.6 V Material categorization: for definitions of compliance 3D Models Design Tools Related Documents please see www.vishay.com/doc 99912 DESCRIPTION PROXIMITY FUNCTION VCNL3040 integrates a proximity sensor (PS), and a high Immunity to red glow (940 nm IRED) power IRED into one small package. It incorporates Programmable IRED sink current photodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process. PS Intelligent cancellation to reduce cross talk programmable interrupt features of individual high and low Smart persistence scheme to reduce PS response time thresholds offers the best utilization of resource and power Selectable for 12-bit / 16-bit PS output data saving on the microcontroller. The 12-bit / 16-bit proximity sensing function uses on INTERRUPT intelligent cancellation scheme, so that cross talk Programmable interrupt function for PS with upper and phenomenon is eliminated effectively. To accelerate the PS lower thresholds response time, smart persistence prevents the misjudgment Adjustable persistence to prevent false triggers for PS of proximity sensing but also keeps a fast response time. Active force mode, one time trigger by one instruction, is APPLICATIONS another good approach for more design flexibility to fulfill different kinds of applications with more power saving. Handheld device PS functions are easily operated via the simple comman d Consumer device 2 format of I C (SMBus compatible) interface protocol. Industrial application Operating voltage ranges from 2.5 V to 3.6 V. VCNL3040 is packaged in a lead (Pb)-free 8 pin QFN package, which offers the best market-proven reliability quality.
