具有低電平有效推挽輸出的微處理器監(jiān)控電路，采用3引腳SOT-23和SC70封裝

ADM809監(jiān)控電路用于監(jiān)控微處理器系統(tǒng)中的電源電壓，可在上電、關斷和掉電情況下提供復位輸出。上電時，內部定時器使復位保持置位狀態(tài)240 ms。這樣，微處理器會保持復位狀態(tài)，直到電源達到穩(wěn)定狀態(tài)。即使VCC低至1 V，/RESET輸出仍然可以工作。ADM809可提供低電平有效復位信號/RESET，還有一個推挽輸出級。\n\n 共提供7種復位閾值選項。復位比較器具有內置抗突波特性，能夠不受VCC的快速瞬變影響。\n\n ADM809提供3引腳SOT-23和SC70兩種封裝，功耗僅為17 μA，適合低功耗便攜式設備使用。 ? 可在整個溫度范圍內提供額定性能 \n\n? 低功耗(17 μA)\n\n? 精密電壓監(jiān)控器：2.5 V、3 V、3.3 V、5 V選項;
