Qualified for automotive applications
The ADuM4400W/ADuM4401W/ADuM4402W1 are 4channel digital isolators based on the Analog Devices, Inc.,
iCoupler® technology. Combining high speed CMOS and
monolithic air core transformer technology, these isolation
components provide outstanding performance characteristics
that are superior to the alternatives, such as optocoupler devices
and other integrated couplers.
The ADuM4400W/ADuM4401W/ADuM4402W isolators
provide four independent isolation channels in a variety of
channel configurations and data rates (see the Ordering Guide).
All models operate with the supply voltage on either side
ranging from 3.135 V to 5.5 V, providing compatibility with
lower voltage systems as well as enabling a voltage translation
functionality across the isolation barrier. The ADuM4400W/
ADuM4401W/ADuM4402W isolators have a patented refresh
feature that ensures dc correctness in the absence of input logic
transitions and during power-up/power-down conditions.
This family of isolators, like many Analog Devices isolators,
offers very low power consumption, consuming one-tenth to
one-sixth the power of comparable isolators at comparable data
rates up to 10 Mbps. All models of the ADuM4400W/
ADuM4401W/ADuM4402W provide low pulse width
distortion ( 0.8 VDD. The common-mode voltage slew rates apply to both
rising and falling common-mode voltage edges.

APPLICATIONS INFORMATION
The ADuM4400W/ADuM4401W/ADuM4402W digital
isolators require no external interface circuitry for the logic
interfaces. Power supply bypassing is strongly recommended
at the input and output supply pins (see Figure 17). Bypass
capacitors are most conveniently connected between Pin 1 and
Pin 2 for VDD1 and between Pin 15 and Pin 16 for VDD2. The
capacitor value should be between 0.01 μF and 0.1 μF. The total
lead length between both ends of the capacitor and the input
power supply pin should not exceed 20 mm. Bypassing between
Pin 1 and Pin 8 and between Pin 9 and Pin 16 should also be
considered unless the ground pair on each package side is
connected close to the package.

SYSTEM-LEVEL ESD CONSIDERATIONS AND
ENHANCEMENTS
System-level ESD reliability (for example, per IEC 61000-4-x)
is highly dependent on system design, which varies widely by
application. The ADuM4400W/ADuM4401W/ADuM4402W
incorporate many enhancements to make ESD reliability less
dependent on system design. The enhancements include:
INPUT (VIx)
50%
tPHL
50%
Figure 18. Propagation Delay Parameters
In applications involving high common-mode transients,
ensure that board coupling across the isolation barrier is
minimized. Furthermore, the board layout should be designed
such that any coupling that does occur equally affects all pins
on a given component side. Failure to ensure this could cause
voltage differentials between pins exceeding the Absolute
Maximum Ratings of the device, thereby leading to latch-up
or permanent damage.
Propagation delay is a parameter that describes the length of
time for a logic signal to propagate through a component. The
propagation delay to a logic low output can differ from the
propagation delay to logic high.

While the ADuM4400W/ADuM4401W/ADuM4402W
improve system-level ESD reliability, they are no substitute for a
robust system-level design. See the AN-793 Application Note,
ESD/Latch-Up Considerations with iCoupler Isolation Products,
for detailed recommendations on board layout and system-level
design.

PC BOARD LAYOUT
ESD protection cells added to all input/output interfaces.
Key metal trace resistances reduced using wider geometry
and paralleling of lines with vias.
The SCR effect, inherent in CMOS devices, minimized by
using guarding and isolation techniques between PMOS
and NMOS devices.
Areas of high electric field concentration eliminated using
45° corners on metal traces.
Supply pin overvoltage prevented with larger ESD clamps
between each supply pin and its respective ground.
Pulse width distortion is the maximum difference between
these two propagation delay values and is an indication of
how accurately the input signal’s timing is preserved.
Channel-to-channel matching refers to the maximum amount
the propagation delay differs among channels within a single
ADuM4400W/ADuM4401W/ADuM4402W component.
Propagation delay skew refers to the maximum amount
the propagation delay differs among multiple ADuM4400W/
ADuM4401W/ADuM4402W components operated under the
same conditions.
DC CORRECTNESS AND MAGNETIC FIELD
IMMUNITY
Positive and negative logic transitions at the isolator input
cause narrow (~1 ns) pulses to be sent via the transformer to
the decoder. The decoder is bistable and is therefore either set
or reset by the pulses, indicating input logic transitions. In the
absence of logic transitions at the input for more than ~1 μs, a
periodic set of refresh pulses indicative of the correct input state
are sent to ensure dc correctness at the output. If the decoder
receives no internal pulses for more than approximately 5 μs,
the input side is assumed to be without power or nonfunctional;
in which case, the isolator output is forced to a default state (see
Table 20) by the watchdog timer circuit.
The limitation on the ADuM4400W/ADuM4401W/
ADuM4402W magnetic field immunity is set by the condition
in which induced voltage in the trans-former’s receiving coil is
large enough to either falsely set or reset the decoder. The
following analysis defines the conditions under which this can
occur. The 3.3 V operating condition of the ADuM4400W/
ADuM4401W/ADuM4402W is examined because it represents
the most susceptible mode of operation.

rn is the radius of the nth turn in the receiving coil (cm).
Given the geometry of the receiving coil in the ADuM4400W/
ADuM4401W/ADuM4402W and an imposed requirement that
the induced voltage be at most 50% of the 0.5 V margin at the
decoder, a maximum allowable magnetic field is calculated as
shown in Figure 19.

Note that at combinations of strong magnetic field and high
frequency, any loops formed by printed circuit board traces may
induce sufficiently large error voltages to trigger the thresholds
of succeeding circuitry. Care should be taken in the layout of
such traces to avoid this possibility.

MAXIMUM ALLOWABLE CURRENT (kA)
The pulses at the transformer output have an amplitude greater
than 1.0 V. The decoder has a sensing threshold at about 0.5 V,
thereby establishing a 0.5 V margin in which induced voltages
can be tolerated. The voltage induced across the receiving coil
is given by
Automotive Products
IDDI = IDDI (Q)
f ≤ 0.5fr
IDDI = IDDI (D) × (2f − fr) + IDDI (Q)
f > 0.5fr
For each output channel, the supply current is given by:
Figure 19. Maximum Allowable External Magnetic Flux Density
For example, at a magnetic field frequency of 1 MHz, the
maximum allowable magnetic field of 0.2 kgauss induces a
voltage of 0.25 V at the receiving coil. This is about 50% of the
sensing threshold and does not cause a faulty output transition.
Similarly, if such an event were to occur during a transmitted
pulse (and was of the worst-case polarity), it would reduce the
received pulse from >1.0 V to 0.75 V—still well above the 0.5 V
sensing threshold of the decoder.
The preceding magnetic flux density values correspond to
specific current magnitudes at given distances away from the
ADuM4400W/ADuM4401W/ADuM4402W transformers.
Figure 20 expresses these allowable current magnitudes as a
function of frequency for selected distances. As can be seen, the
ADuM4400W/ADuM4401W/ADuM4402W are immune and
can be affected only by extremely large currents operated at
high frequency and very close to the component. For the 1 MHz
example noted, one would have to place a 0.5 kA current 5 mm
away from the ADuM4400W/ADuM4401W/ADuM4402W to
affect the component’s operation.

ADuM4400W/ADuM4401W/ADuM4402W
All insulation structures eventually break down when subjected
to voltage stress over a sufficiently long period. The rate of
insulation degradation is dependent on the characteristics of
the voltage waveform applied across the insulation. In addition
to the testing performed by the regulatory agencies, Analog
Devices carries out an extensive set of evaluations to determine
the lifetime of the insulation structure within the ADuM4400W/
ADuM4401W/ADuM4402W.
Analog Devices performs accelerated life testing using voltage
levels higher than the rated continuous working voltage. Acceleration factors for several operating conditions are determined. These
factors allow calculation of the time to failure at the actual working
voltage. The values shown in Table 19 summarize the peak voltage
for 50 years of service life for a bipolar ac operating condition and
the maximum CSA/VDE approved working voltages. In many
cases, the approved working voltage is higher than the 50-year
service life voltage. Operation at these high working voltages
can lead to shortened insulation life in some cases.
In the case of unipolar ac or dc voltage, the stress on the insulation is significantly lower. This allows operation at higher
working voltages while still achieving a 50-year service life.
The working voltages listed in Table 19 can be applied while
maintaining the 50-year minimum lifetime, provided the
voltage conforms to either the unipolar ac or dc voltage cases.
Any cross-insulation voltage waveform that does not conform
to Figure 22 or Figure 23 should be treated as a bipolar ac waveform, and its peak voltage should be limited to the 50-year
lifetime voltage value listed in Table 19.
Note that the voltage presented in Figure 22 is shown as sinusoidal for illustration purposes only. It is meant to represent any
voltage waveform varying between 0 V and some limiting value.
The limiting value can be positive or negative, but the voltage
cannot cross 0 V.
The insulation lifetime of the ADuM4400W/ADuM4401W/
ADuM4402W depends on the voltage waveform type imposed
across the isolation barrier. The iCoupler insulation structure
degrades at different rates, depending on whether the waveform
is bipolar ac, unipolar ac, or dc. Figure 21, Figure 22, and
Figure 23 illustrate these different isolation voltage waveforms.
