5 terms

vcsel technical

"Featuring a vertical-cavity surface-emitting laser (VCSEL)"

A VCSEL is a tiny semiconductor laser that emits light straight out of the surface of a chip, like a miniature, very precise flashlight built into an electronic component. Investors care because VCSELs are key parts in optical communication, sensors, and proximity or gesture controls—products with growing demand—so changes in VCSEL supply, cost or adoption can affect a maker’s sales, margins and the competitive position of companies that rely on them.

asic technical

"application-specific integrated circuit (ASIC), 16-bit ADC"

ASIC is Australia’s corporate, markets and financial services regulator that enforces rules for companies, financial advisers and market operators; think of it as the referee and rulebook keeper for financial activity. It matters to investors because ASIC’s oversight, investigations and enforcement actions affect company credibility, legal risk and market fairness—actions that can change stock prices, investor confidence and the safety of financial products.

16-bit adc technical

"combines a photodiode, application-specific integrated circuit (ASIC), 16-bit ADC"

A 16-bit ADC is an analog-to-digital converter that turns continuous real-world signals (like voltage from a sensor) into digital numbers using 16 bits of resolution, which yields 65,536 distinct levels. Think of it as a ruler with 65,536 ticks: finer ticks let you measure small changes more precisely. For investors, bit depth affects a device’s measurement accuracy, product performance, manufacturing cost, and suitability for precision applications.

i²c slave address technical

"smart dual I²C slave address in a compact 1.6 mm x 1.0 mm"

A i²c slave address is the unique numeric identifier assigned to a device on an I²C (inter-integrated circuit) communication bus so the controller (master) can send data to or request data from that specific device. Think of it like a house number on a shared street: it prevents messages meant for one device from going to another. For investors, it matters because address conflicts, limited address space, or nonstandard implementations can affect product compatibility, development time and integration costs.

rohs-compliant regulatory

"The sensor is RoHS-compliant, halogen-free, and Vishay Green."

RoHS-compliant means a product meets rules that limit or ban certain hazardous chemicals in electrical and electronic equipment, ensuring the item does not contain those restricted substances above set limits. For investors this matters because compliance affects a company's ability to sell in regulated markets, avoid fines and recalls, and manage production costs and supply-chain risks—similar to a food product following a recipe that omits banned ingredients to stay sellable and safe.

Featuring a VCSEL and Smart Dual I²C Slave Address, Space-Saving Device Is Ideal for Battery-Powered Consumer Applications, Including TWS Earphones and VR / AR Headsets

MALVERN, Pa., Aug. 18, 2026 (GLOBE NEWSWIRE) -- The Optoelectronics group of Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new fully integrated short distance proximity sensor designed to increase efficiency, design flexibility, and performance in consumer applications. Featuring a vertical-cavity surface-emitting laser (VCSEL), the Vishay Semiconductors VCNL36829UM combines a photodiode, application-specific integrated circuit (ASIC), 16-bit ADC, and smart dual I²C slave address in a compact 1.6 mm x 1.0 mm x 0.35 mm transparent mold package with an isolation wall design.

Compared to previous-generation solutions, the proximity sensor released today offers a 44 % smaller volume, higher proximity resolution of 14 bits, and stronger sunlight immunity up to 200 klx. Combined with a range of 50 mm, low idle current of 5 μA, and a typical rated supply voltage of 1.8 V, the VCNL36829UM delivers superior proximity detection while reducing power consumption to increase efficiency in space-constrained, battery-powered applications.

The sensor is designed to detect if users are wearing or not wearing smart wearable devices, including true wireless stereo (TWS) earphones, virtual reality / augmented reality (VR / AR) headsets, and smart glasses. It is also suitable for touchless dispensing and lid-off detection in consumer appliances. To lower costs in these applications, the device’s smart dual I²C slave address allows for the connection of two proximity sensors without the need for a multiplexer.

The VCNL36829UM offers a programmable interrupt function that allows designers to specify high and low thresholds, reducing continuous communication with the microcontroller and lowering system power consumption. The sensor’s isolation wall design delivers excellent crosstalk immunity. The device uses intelligent cancellation to further reduce crosstalk, 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 sensor is RoHS-compliant, halogen-free, and Vishay Green.
