ADM707

低成本微處理器監(jiān)控電路; ? 保證 RESET 有效（VCC = 1 V ）\n\n? 靜態(tài)電流：190 μA\n\n? 精密電源電壓監(jiān)控器\n4.65 V (ADM705/ADM707) \n4.40 V (ADM706/ADM708) \n\n? 復(fù)位脈沖寬度：200 ms\n\n? 去抖TTL/CMOS手動復(fù)位輸入(MR);

ADM705/ADM706/ADM707/ADM708微處理器監(jiān)控電路均適合監(jiān)控5 V電源/電池，也可用于監(jiān)控微處理器活動。\n\n ADM705/ADM706提供電源監(jiān)控電路，該電路可在上電、關(guān)斷和掉電情況下產(chǎn)生復(fù)位輸出。即使VCC低至1 V，復(fù)位輸出仍然可以工作。還提供獨(dú)立的看門狗監(jiān)控電路。如果看門狗輸入在1.60秒內(nèi)未觸發(fā)，該電路會被激活。 \n\n 此外還集成一個1.25 V閾值檢測器，用于發(fā)出電源故障警告、檢測低電池電量或監(jiān)控附加電源。另外還提供低電平有效、去抖手動復(fù)位輸入(MR)。\n\n 除了復(fù)位閾值監(jiān)控電平分別為4.65 V和4.40 V以外，ADM705和ADM706兩者幾乎相同。 。\n\n ADM707和ADM708的功能與ADM705和ADM706類似，唯一不同之處是不提供看門狗定時器功能。 相反，它們具有高電平有效復(fù)位輸出(RESET)和低電平有效復(fù)位輸出(RESET)。 除了復(fù)位閾值監(jiān)控電平分別為4.65 V和4.40 V以外，ADM707和ADM708兩者幾乎相同。 \n\n 所有器件均提供8引腳窄體PDIP和8引腳SOIC兩種封裝。 \n\n
