Mouser Now Offers Vishay’s VCNL4100 Long-Distance Proximity and Ambient Light Sensor

Vishay’s VCNL4100

Mouser Electronics announces stocking of new VCNL4100 proximity and ambient light sensor from Vishay. The new device 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.

Exclusive at Mouser, the new Vishay’s VCNL4100 proximity and ambient light sensor 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 dark or high-transparency lenses 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.

Additionally, 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.
