VCNL36825T integrates a proximity sensor (PS), and a VCSEL 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.
The 12-bit proximity sensing function uses on intelligent cancellation scheme, so that cross talk phenomenon is eliminated effectivitely. 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 saving. Low power consumption mode offer the significantly power saving for any application requirements.
The adoption of Vishay Capella's unique spectrum technology achieves the best light filter funciton. VCNL36825T provides an excellent temperature compensation capability for keeping output stable under various temperature configurations. PS functions are easily operated via the simple command format of I2C (SMBus compatible) interface protocol. Operating voltage ranges from 2.62 V to 3.6 V. VCNL36825T is packaged in a lead-free 8 pin molding package, which offers the best market-proven reliability quality.
