November 22, 2016 – Mouser Electronics, Inc., the industry’s leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the VCNL4100 proximity and ambient light sensor from Vishay. The high-sensitivity VCNL4100 combines a high-power infrared (IR) emitter, photo detectors for proximity and ambient light, a signal-processing IC, and an 8-bit/16-bit analog-to-digital converter (ADC) to provide long-distance proximity and presence detection up to 1 meter for smart home, robotics, lighting control, and vehicle detection applications.
Vishay’s VCNL4100 proximity and ambient light sensor, available from Mouser Electronics, offers a five-fold increase in proximity detection over previous-generation devices. The sensor’s integrated long-distance proximity sensor, ambient light sensor, and 940nm infrared-emitting diode (IRED) eliminate the need for additional light barriers and optical alignment of the IR emitter and photo diode. The device’s small outline saves space and gives design engineers greater flexibility in where and how they locate the sensor.
The VCNL4100 device’s 16-bit, high-resolution ambient light sensor offers excellent sensing capabilities with sufficient selections to fulfill most applications whether a dark or high-transparency lens design. The devices offers individual programmable high- and low-threshold interrupt features to allow designers to best utilize resources and power on the microcontroller. For the 8-bit proximity-sensing function, VCNL4100 has a built-in intelligent cancelation scheme that eliminates background light issues. The device’s smart persistence scheme prevents false judgment of proximity sensing due to ambient light noise.
The VCNL4100 provides temperature compensation of -40 to +85 degrees Celsius to keep the output stable under changing temperature. Designers can easily operate proximity and ambient light sensor functions via the device’s I2C (SMBus-compatible) interface protocol. The device operates on a supply voltage range of 2.5 V to 3.6 V in a lead-free, RoHS-compliant 8.0 × 3.0 × 1.8mm package.
