TECHNOLOGY: Proximity Sensor Trims Power Consumption

To boost efficiency and performance in consumer and industrial designs, Vishay Intertechnology is introducing the VCNL36825T integrated proximity sensor. To increase efficiency, the device specifies a power consumption down to 6.63 μA.

Integrating a vertical-cavity surface-emitting laser (VCSEL), the VCNL36825T combines a photodiode, signal processing IC and a 12-bit analog-to-digital converter (ADC) in a 2 mm x 1.25 mm x 0.5 mm surface-mount package with a 1.6-mm light hole. The compact device is viable and desirable for use in tight-quarter applications, such as detecting true wireless stereo (TWS) earphones or virtual and augmented reality (VR / AR) headsets. With a range of 200 mm, it also provides collision detection in toys and consumer and industrial robots.

Other features of the VCNL36825T include an I²C bus, intelligent cancellation to eliminate cross-talk, a smart persistence scheme, reliable temperature compensation from -40°C to +85°C and a Moisture Sensitivity Level (MSL) of 3, in accordance with J-STD-020 for a floor life of 168 hours. Additionally, the VCSEL wavelength peaks at 940 nm and exhibits no visible red tail.

Samples and production quantities of the VCNL36825T are available now, with lead times of eight to 12 weeks for large orders. Pricing for US delivery starts at $0.60 each/5,000.

For deeper details and brighter illuminations, procure and peruse the VCNL36825T datasheet. For even higher wisdom, you may want to review the VCNL36825T application note and selector guide.
