Vishay Intertechnology’s New Proximity Sensor Offers Idle Current Down to 5 μA in Compact 2.0 mm x 1.0 mm x 0.5 mm SMD Package
January 25 2024 - 11:00AM
The Optoelectronics group of Vishay Intertechnology, Inc. (NYSE:
VSH) today introduced a new fully integrated proximity sensor
designed to increase efficiency and performance in consumer
applications. Featuring a vertical-cavity surface-emitting laser
(VCSEL), the Vishay Semiconductors VCNL36828P combines a
photodiode, application-specific integrated circuit (ASIC), 16-bit
ADC, and smart dual I²C slave address in a compact 2.0 mm by 1.0 mm
by 0.5 mm surface-mount package.
Compared to previous-generation solutions, the proximity sensor
released today offers a 20 % smaller package, 20 % lower idle
current of 5 μA, and 40 % higher sunlight cancellation up to 140
klx. With a range of 200 mm and a typical rated supply voltage of
1.8 V, the device is designed to deliver superior proximity
detection while reducing power consumption to increase efficiency
in space-constrained, battery-powered applications.
The proximity sensor will be used in smartphones and smart
watches for automatic screen wake-up and turn-off functions, in
addition to detecting if users are wearing or not wearing true
wireless stereo (TWS) earphones, virtual reality / augmented
reality (VR / AR) headsets, and smart glasses. To lower costs in
these applications, the VCNL36828P’s smart dual I²C slave address
allows for the connection of two proximity sensors without the need
for a multiplexer.
The device offers a programmable interrupt function that allows
designers to specify high and low thresholds to reduce continuous
communication with the microcontroller. The VCNL36828P uses
intelligent cancellation to reduce cross-talk, while a smart
persistence scheme ensures accurate sensing and a faster response
time. The VCSEL wavelength peaks at 940 nm and has no visible
“red-tail.” The sensor is RoHS-compliant, halogen-free, and Vishay
Green.
