DESCRIPTION
please see www.vishay.com/doc?99912 VCNL3040 integrates a proximity sensor (PS), and a high
PROXIMITY FUNCTION
power IRED into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting • Immunity to red glow (940 nm IRED) circuits into a single chip by CMOS process. PS • Programmable IRED sink current programmable interrupt features of individual high and low • Intelligent cancellation to reduce cross talk thresholds offers the best utilization of resource and power • Smart persistence scheme to reduce PS response time saving on the microcontroller. • Selectable for 12-bit / 16-bit PS output data The 12-bit / 16-bit proximity sensing function uses on intelligent cancellation scheme, so that cross talk
INTERRUPT
phenomenon is eliminated effectively. To accelerate the PS response time, smart persistence prevents the misjudgment • Programmable interrupt function for PS with upper and of proximity sensing but also keeps a fast response time. lower thresholds Active force mode, one time trigger by one instruction, is • Adjustable persistence to prevent false triggers for PS another good approach for more design flexibility to fulfill different kinds of applications with more power saving.
APPLICATIONS
The VCNL3040 provides an excellent temperature • Handheld device compensation capability for keeping output stable under • Consumer device various temperature configurations. PS functions are easily operated via the simple command format of I2C (SMBus • Industrial application compatible) interface protocol. 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.
