微處理器監(jiān)控電路，內(nèi)置看門狗功能、4.65 V閾值電壓、低電源電流及低電平有效復(fù)位輸出特性，ADM699的升級產(chǎn)品

ADM8698/ADM8699監(jiān)控電路針對微處理器系統(tǒng)提供電源監(jiān)控和看門狗定時功能。\n\n 在上電和關(guān)斷期間，以及在低壓“掉電”情況下，ADM8698監(jiān)控5 V VCC 電源，并產(chǎn)生一個RESET脈沖。即使 VCC 低至1 V，也能保證RESET輸出有效（邏輯低電平）。\n\n ADM8699具有一個與ADM8698相同的監(jiān)控電路，另外還有一路看門狗定時器輸入，用來監(jiān)控微處理器的活動。如果看門狗輸入在1秒的看門狗超時周期內(nèi)未觸發(fā)，則會強制RESET輸出變?yōu)榈碗娖?。\n\n 這兩款器件均提供8引腳塑封DIP/SOIC和16引腳SOIC封裝。16引腳SOIC含有附 ? 出眾的ADM698/ADM699、MAX698/MAX699升級產(chǎn)品\n? 保證RESET置位（VCC = 1 V）\n? 低電源電流：70 μA\n? 4.65 V精密電壓監(jiān)控器;
