ADM6711:  Microprocessor Supervisory Circuit in 4-Lead SC70

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.

ADM6711:  Microprocessor Supervisory Circuit in 4-Lead SC70

Product Description

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.

The parts are highly reliable with accurate voltage references and immunity to fast, negative-going transients on VCC. Low current consumption and space-efficient, 4-lead SC70 packaging make the ADM6711/ADM6713 ideal for use in low power portable applications.
