Vishay Intertechnology公司（纽约证券交易所:VSH）今天推出了一款全新的全集成式接近传感器，旨在提高消费应用的效率和性能。Vishay半导体采用垂直腔面发射激光器（VCSEL）VCNL36828P贴片晶振将光电二极管、专用集成电路（ASic）、16位ADC和智能双通道IC从机地址集成在一个2.0mmx1.0mmx0.5mm的紧凑表贴封装中。

与上一代解决方案相比，今天发布的近程传感器提供了20%的更小封装，5μA的空闲电流降低了20 %，140klx的阳光消除率提高了40%。该器件的范围为200mm，典型额定电源电压为1.8V有源晶振，旨在提供出色的接近检测性能，同时降低功耗，以提高空间受限的电池供电应用的效率。

接近传感器将用于智能手机和智能手表中的自动屏幕唤醒和关闭功能，此外还可以检测用户是否佩戴真无线立体声（TWS）耳机、虚拟现实/增强现实（VR/AR）耳机和智能眼镜。为了降低这些应用的成本，VCNL36828P的智能双通道I C从机地址允许连接两个接近传感器，而无需多路复用器。

该器件提供可编程中断功能，允许设计人员指定高阈值和低阈值，以减少与微控制器的持续通信。VCNL36828P石英晶振使用智能消除来减少串扰，而智能持续方案可确保准确的感知和更快的响应时间。VCSEL波长峰值在940纳米，没有可见的“红尾”该传感器符合RoHS标准，无卤素，Vishay绿色。

Vishay超小型VCNL36828P可提供低至5μA的空闲电流

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.
