SC70微處理器監(jiān)控電路ADM6711/ADM6713數(shù)據(jù)表

　　The ADM6711/ADM6713 are reset generator circuits suitable for use in microprocessor-based systems. They provide a reset signal on power-up， power-down， and whenever the supply voltage falls below a preset threshold. In addition， both parts have a debounced manual reset input so that a reset signal can also be initiated with an external switch or logic signal. With six different reset threshold options available ranging from 2.32 V to 4.63 V， the ADM6711/ADM6713 are suitable for monitoring 2.5 V， 3 V， 3.3 V， and 5 V supplies. A reset timeout of at least 140 ms occurs when VCC rises above the threshold. This gives the supply voltage time to stabilize before the microprocessor starts up. The ADM6711 has a push-pull output， so no additional external components are needed. The ADM6713 open-drain output requires an external pull-up resistor that can be connected to a voltage higher than VCC， if desired.
