VISHAY VCNL36687S

VCNL36687S integrates a proximity and a high power VCSEL (vertical- cavity surface- emitting laser) into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process. PS programmable interrupt features of individual high and low thresholds offers the best utilization of resource and power saving on the microcontroller. With just 20 mA pulse current, the VCNL36687S can detect the Kodak Gray Card in a distance of 20 cm where other sensors need 200 mA. The 12 bits proximity sensing function uses an intelligent cancellation scheme, so that cross talk is eliminated effectively. To accelerate the PS response time, smart persistence prevents the misjudgment of proximity sensing but also allows for a fast response time. Active force mode, one time trigger by one instruction, is a feature offering more power saving. PS functions are easily operated via the simple command format of I²C (SMBus compatible) interface protocol. Operating voltage ranges from 1.65 V to 1.95 V. VCNL36687S is packaged in a lead (Pb)- free 8 pin molding package, which offers the best market- proven reliability quality.
