【文字介紹】

Vishay推出具有節能中斷功能的全集成接近和環境光光學感測器,擴大其光電子產品組合。VCNL4010 & VCNL4020將用於接近探測的紅外發射器和光電二極體、環境光探測器、信號處理IC和一個16位元ADC全部組合進小尺寸3.95mm x 3.95mm x 0.75mm & 4.9mm x 2.4mm x 0.83mm的無引線(LLP)表面貼裝封裝內。這款節省空間的器件支援易用的I2C匯流排通信介面,大大簡化了在各種消費和行業應用中接收視窗和感測器的設計。

VCNL4010 & VCNL4020的中斷功能使感測器能夠一直獨立工作,直到發生預先定義的接近和環境光事件,VCNL4010 & VCNL4020才喚醒微控制器。這樣有利於客戶減少在軟體上花的功夫,避免在感測器和微控制器之間產生輪詢通信流量,從而降低功耗。

對於智慧手機、觸控式螢幕手機、PDA、GPS單元和數碼相機,以及計算和工業設備及顯示器,新的VCNL4010 & VCNL4020能夠用作鎖定觸控式螢幕的接近感測器,達到節能的目的,還可以用做顯示幕/按鍵的對比度控制和調光的集成環境光功能。VCNL4010 & VCNL4020在一個器件裡就包含了這些應用所需要的全部電路,不再需要機械光柵,也不需要紅外發射器和光電二極體在光路上保持對齊。

感測器的16位有效解析度使其在進行接近探測時能夠很好地抵禦串擾。其他產品對物體的最遠探測距離只有100mm,而VCNL4010 & VCNL4020的可程式設計LED驅動電流達到10mA~200mA(以10mA遞增),使探測距離可以達到200mm。器件對紅外發射器的信號進行了調製,具有優異的抑制環境光能力。
