The new fully integrated VCNL36825T proximity sensor from Vishay Intertechnology offers power consumption down to 6.63 µA in a 2.0 mm x 1.25 mm x 0.5 mm SMD package. The small size of this device makes it ideal for space-constrained battery-powered applications, such as detecting if users are wearing or not wearing true wireless stereo (TWS) earphones or virtual reality / augmented reality (VR / AR) headsets.


Featuring a VCSEL and small 1.6 mm light hole, this compact device combines a photodiode, signal processing IC, and 12-bit ADC in a small package. Compared to previous-generation devices, the newly released proximity sensor offers a 76% smaller package, while reducing light hole opening provides increased design flexibility at a comparatively lower cost. 


With a range of 200 mm, the proximity sensor provides collision detection in toys and consumer and industrial robots. It features low power consumption down to 6.63 µA to increase efficiency in these applications. Moreover, it supports the I²C bus communication interface for easy access to the proximity signal, while its programmable interrupt function enables designers to specify high and low thresholds to reduce the continuous communication with the microcontroller. 


Using intelligent cancellation, the proximity sensor talked about eliminates cross-talk while a smart persistence scheme ensures accurate sensing and faster response time. The VCSEL wavelength peaks at 940 nm and has no visible red-tail. The device offers excellent 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. It is RoHS-compliant, halogen-free, and Vishay Green.
