Vishay Semiconductors VCNL36758 Medium Distance Proximity Sensor
Vishay Semiconductor VCNL36758 Medium Distance Proximity Sensor integrates a high-sensitivity proximity sensor (PS) and an IR LED into one single package. It incorporates a photodiode, amplifiers, and analog/digital circuits into a single chip using the CMOS process. VCNL36758 offers individual programmable high and low threshold interrupt features, enabling the utilization of resources and power savings on the microcontroller.
The 12-bit proximity sensing function utilizes an intelligent cancellation scheme, effectively eliminating crosstalk. 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, a one-time trigger enabled by a single instruction, is a feature that offers more power savings.
The Vishay Semiconductor VCNL36758 offers excellent temperature compensation capabilities, maintaining stable output under various temperature conditions. PS functions are easily operated via the simple command format of the I2C (SMBus compatible) interface protocol. VCNL36758’s operating voltage ranges from 1.7V to 3.6V and is packaged in a lead-free 10-pin molding package, which offers market-proven reliability.
