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.
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.
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.

CIRCUIT DESCRIPTION
ADM6713
OUTPUT LOGIC LEVELS
RESET
The ADM6711/ADM6713 are designed to protect the integrity
of a system’s operation by ensuring the proper operation of the
system during power-up, power-down, and brownout conditions.
The ADM6713 open-drain
output is designed for use
RESET
with an external pull-up resistor. This resistor can be tied to VCC
or any other reasonable voltage level, offering the flexibility
to use the ADM6713 to drive a variety of different logic level
circuitry.
When the ADM6711/ADM6713 are powered up, the
RESET
output remains low for a period equal to the typical reset active
timeout period. This is designed to give the system time to
power up correctly and for the power supply to stabilize before
any devices are brought out of reset and allowed to begin
executing instructions. Initializing a system in this way provides
a more reliable startup for microprocessor systems.

The ADM6711/ADM6713 contain internal filtering circuitry

Glitch immunity makes the ADM6711/ADM6713 suitable for

immunity further.
