Vishay Intertechnology公司（紐約證券交易所:VSH）今天推出了一款全新的全集成式接近傳感器，旨在提高消費應用的效率和性能。Vishay半導體采用垂直腔面發射激光器（VCSEL）VCNL36828P貼片晶振將光電二極管、專用集成電路（ASic）、16位ADC和智能雙通道IC從機地址集成在一個2.0mmx1.0mmx0.5mm的緊湊表貼封裝中。

與上一代解決方案相比，今天發布的近程傳感器提供了20%的更小封裝，5μA的空閑電流降低了20 %，140klx的陽光消除率提高了40%。該器件的范圍為200mm，典型額定電源電壓為1.8V有源晶振，旨在提供出色的接近檢測性能，同時降低功耗，以提高空間受限的電池供電應用的效率。

接近傳感器將用于智能手機和智能手表中的自動屏幕喚醒和關閉功能，此外還可以檢測用戶是否佩戴真無線立體聲（TWS）耳機、虛擬現實/增強現實（VR/AR）耳機和智能眼鏡。為了降低這些應用的成本，VCNL36828P的智能雙通道I C從機地址允許連接兩個接近傳感器，而無需多路復用器。

該器件提供可編程中斷功能，允許設計人員指定高閾值和低閾值，以減少與微控制器的持續通信。VCNL36828P石英晶振使用智能消除來減少串擾，而智能持續方案可確保準確的感知和更快的響應時間。VCSEL波長峰值在940納米，沒有可見的“紅尾”該傳感器符合RoHS標準，無鹵素，Vishay綠色。

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

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

MALVERN, Pa., Jan. 25, 2024 (GLOBE NEWSWIRE) -- 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.
