Microprocessor Supervisory Circuits in 3-Lead SC70 and SOT-23

GENERAL DESCRIPTION The ADM803/ADM809/ADM810 supervisory circuits monitor the power supply voltage in microprocessor systems. They provide a reset output during power-up, power-down, and brownout conditions. On power-up, an internal timer holds reset asserted for 240 ms. This holds the microproce

具有低電平有效開漏輸出的微處理器監(jiān)控電路，采用3引腳SC70封裝

ADM803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1V，復位輸出仍然可以工作。ADM803可提供低電平有效復位信號RESET，還有一個開漏輸出級，后者需要一個外部上拉電阻。\n\n 共提供7種復位閾值選項。復位比較器具有內置干擾抑制特性，能夠不受VCC上的快速瞬變影響。\n\n ADM803采用3引腳SC70封裝，功耗僅17μA，適合低功耗便攜式設備使用。 ? 整個溫度范圍內保證特性\n\n? 低功耗(17 μA)\n\n? 精密電壓監(jiān)控器：提供2.5 V、3 V、3.3 V、5 V選項;
