產(chǎn)品簡述:
R3111x系列是基于cmos的電壓檢測器ic,具有很高的檢測器閾值精度和超低的電源電流,可以在極低的電壓下工作,用于系統(tǒng)復(fù)位為例。
每個集成電路都由電壓參考單元、比較器、用于檢測器閾值設(shè)置的電阻、輸出驅(qū)動器和遲滯電路組成。檢測器閾值內(nèi)部固定,精度高,不需要調(diào)整。
有三種輸出類型,Nch開漏“L”型,Nch開漏“H”型和CMOS型。
R3111x系列的操作電壓比Rx5VL系列的低,并可以由單個電池驅(qū)動。
有TO-92、SOT-89、SOT-23-3、SOT-23-5、SC-82AB、SC-88A和SON1612-6七種封裝可供選擇。
應(yīng)用程序:
CPU和邏輯電路復(fù)位
電池檢查
窗口比較器
波浪整形電路
