Data Sheet
THEORY OF OPERATION
INTERFACING TO OUTPUT OF OTHER DEVICES
The ADM6315 series is designed to integrate with as many
devices as possible. One feature of the ADM6315 is the RESET
open-drain output, which can sink current from sources with a
voltage greater than the V CC of the ADM6315 input, making it
suitable for use in more diverse applications.
BENEFITS OF A VERY ACCURATE RESET THRESHOLD
Because the ADM6315 series can operate effectively even when
there are large degradations of the supply voltages (due to an
accurate internal voltage reference circuit), the possibility of a
malfunction during a power failure is greatly reduced.

MANUAL RESET INPUT
The ADM6315 also provides an additional input, MR. This
input can be used either as a means for the system operator to
reset the system manually via a switch or for a digital circuit to
reset the system.
The MR input (typically) ignores negative-going pulses that are
faster than 100 ns, and it is guaranteed to accept any negative-
going input pulse of a duration greater than or equal to 1 μs. If
MR is connected to long cables or is used in a noisy environment,
placing a 1 μF decoupling capacitor between the MR input and

DETAILED DESCRIPTION
The ADM6315 is 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 ADM6315 is powered up, the RESET output of the
ADM6315 remains low for a period typically equal to the RESET
active timeout period. This feature allows adequate time for the
system to power up correctly and for the power supply to
stabilize before any devices are brought out of reset and allowed

TRANSIENT IMMUNITY
As well as being an accurate reset circuit, the ADM6315 has

reset threshold) vs. the pulse duration without a reset.
to begin executing instructions. Initializing a system in this way
provides a more reliable startup for microprocessor systems.
When a brownout condition occurs (assuming V CC is falling at
1 mV/μs), the ADM6315 produces a reset in 35 μs typical.
Producing a reset this fast means that the entire system can be
reset together before any part of the system’s voltage falls below
its recommended operating voltage. This system reset can avoid
dangerous and/or erroneous operation of a microprocessor-
based system.
