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 volt-

age 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

This gives the supply voltage time to stabilize before the micro-

processor starts up.

The ADM6711 has a push-pull output, so no additional external

components are needed. The ADM6713’s open-drain output

requires an external pull-up resistor, which can be connected to a

The parts are highly reliable with accurate voltage references

current consumption and space-efficient 4-lead SC70 packaging

make the ADM6711/ADM6713 ideal for use in low power

portable applications.
