微處理器監(jiān)控電路

MAX690A/MAX692A/MAX802L/MAX802M/MAX805L監(jiān)控電路減少了微處理器(μP)系統(tǒng)中的電源監(jiān)控和電池控制功能所需的復(fù)雜性和元件數(shù)量。與單獨(dú)的IC或分立元件相比，它們顯著提高了系統(tǒng)的可靠性和準(zhǔn)確性。\n\n 這些器件提供四個(gè)功能：1) 啟動(dòng)、關(guān)斷和掉電情況下的復(fù)位輸出。2) CMOS RAM、CMOS μP或其他低功耗邏輯的備用電池切換。3)如果可選的看門狗定時(shí)器在1.6秒內(nèi)未切換，則提供復(fù)位脈沖。4) 1.25V閾值檢測(cè)器，用于電源故障警告、低電池電量檢測(cè)或+5V以外電源的監(jiān)控。\n\n 這些器件的復(fù)位電壓閾值電平和復(fù)位輸出有所不同。MAX69 ? 精密電源電壓監(jiān)控器：\n? MAX690A/MAX802L/MAX805L為4.65V\n\n? MAX692A/MAX802M為4.40V\n\n\n\n\n? 復(fù)位時(shí)間延遲：200ms\n\n? 看門狗定時(shí)器：1.6s超時(shí)\n\n? 備用電池電源開關(guān)\n\n? 靜態(tài)電源電流：200μA\n\n? 備用電池模式下的靜態(tài)電源電流為50nA\n\n? 電壓監(jiān)控器，監(jiān)控有無電源故障或低電池電量警告\n\n? 電源故障精度高達(dá)±2% (MAX802L/M)\n\n? 低至 VCC = 1V 時(shí)確保低電平有效RESET置位\n\n? 8引腳SO和DIP封裝;
