Vishay Intertechnology High Sensitivity Proximity and Ambient Light Sensor Offers Increased Proximity Detection to 1.5 Meters...
July 10 2017 - 10:00AM
The Optoelectronics group of Vishay Intertechnology, Inc.
(NYSE:VSH) today introduced a new high sensitivity proximity and
ambient light sensor that combines long distance proximity
detection up to 1.5 m with Filtron™ technology in a compact
8 mm by 3 mm by 1.8 mm surface-mount package. The Vishay
Semiconductors VCNL4200 three in one sensor features a high power
IR emitter, photo detectors for proximity and ambient light, a
signal processing IC, and a 12-bit / 16-bit ADC, while providing an
interrupt function and supporting I²C bus communication interface
for smart home, industrial, and office applications.
Offering a 50% increase in proximity detection over
previous-generation devices, the VCNL4200 provides presence
detection for display activation in printers, copiers, and home
appliances; collision avoidance in toys and robots; proximity
sensing and lighting control in offices, corridors, and public
buildings; lavatory appliance activation; and parking space
availability in lots and garages. Containing the circuitry needed
for these applications in one device, the sensor eliminates 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 ambient light and proximity sensors of the VCNL4200 operate
in a parallel structure, and each offers a programmable interrupt
function with high and low thresholds that allow the sensor to wake
up an application from a low power mode, reducing the overall power
consumption of an application. The device’s Filtron technology
enables ambient light spectral sensitivity close to that of the
human eye while offering excellent background light cancellation
capabilities.
The VCNL4200’s built-in ambient light photo diode offers
detection from 0.003 lx to 1.57 klx, allowing the device to operate
in applications with dark or high transparency lens designs. The
16-bit sensor offers fluorescent light flicker immunity and
excellent temperature compensation from -40 °C to +85 °C. The
VCNL4200’s 12-bit proximity sensor uses intelligent cancellation to
eliminate cross-talk, while a smart persistence scheme ensures
accurate sensing and faster response time. The emitter wavelength
peaks at 940 nm and has no visible “red-tail.”
The device offers a supply voltage range of 2.5 V to 3.6 V and
I²C bus voltage range from 1.8 V to 3.6 V. Offered in a lead
(Pb)-free 10-pin QFN package, the sensor is RoHS-compliant,
halogen-free, and Vishay Green.
Samples and production quantities of the new VCNL4200 are
available now, with lead times of eight to 12 weeks for large
orders.
