GENERAL 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 V

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 V

The parts are highly reliable with accurate voltage references

and immunity to fast, negative-going transients on V

current consumption and space-efficient, 4-lead SC70

packaging make the ADM6711/ADM6713 ideal for use in low

power portable applications.
