ADM6711/ADM6713
DETAILED DESCRIPTION
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.
When the ADM6711/ADM6713 are powered up, the
RESET
output will remain 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.
MANUAL RESET INPUT
The ADM6711/ADM6713’s manual reset (
MR
) input allows
the system operator to reset a system by means of an external
manual switch. Alternatively, a logic signal from another digital
circuit can be used to trigger a reset via the
MR
input.
The
MR
input will ignore negative-going pulses faster than
100 ns (typically) and is guaranteed to accept any negative-
going input pulse of a duration greater than or equal to 1
μ
s.
The
RESET
output will remain low while
MR
is held low and
for 240 ms (typically) after
MR
returns high.
If
MR
is connected to long cables or is used in a noisy environ-
ment, then placing a 0.1
μ
F capacitor between the
MR
input
and ground will help to remove any fast, negative-going transients.
POWER SUPPLY GLITCH IMMUNITY
The ADM6711/ADM6713 contain internal filtering circuitry
that provides immunity to fast transient glitches on the power
supply line. TPC 6 illustrates glitch immunity performance by
showing the maximum transient duration without causing a
reset pulse for glitches with amplitudes in the range of 1 mV to
1000 mV.
Glitch immunity makes the ADM6711/ADM6713 suitable for
use in noisy environments. Mounting a 0.1
μ
F decoupling
capacitor as close as possible to the V
CC
pin improves glitch
immunity further.

RESET
OUTPUT LOGIC LEVELS
The ADM6713’s open-drain
RESET
output is designed for use
with an external pull-up resistor. This resistor can be tied to V
CC
or any other reasonable voltage level, offering the flexibility to use
the ADM6713 to drive a variety of different logic level circuitry.

= 0 V
When V
CC
falls below 0.8 V, the ADM6711’s
RESET
output no
longer sinks current. Therefore, a high impedance CMOS logic
input connected to
RESET
may drift to undetermined logic
levels. To eliminate this problem, a pull-down resistor should be
connected from
RESET
to ground. A 100 k
resistor is large
enough not to load
RESET
and small enough to pull
RESET
to ground.
