GENERAL DESCRIPTION
ID
The ADuM6400/ADuM6401/ADuM6402/ADuM6403/
ADuM64041 are quad-channel digital isolators with isoPower®,
an integrated, isolated dc-to-dc converter. Based on the Analog
Devices, Inc., iCoupler® technology, the dc-to-dc converter provides
up to 400 mW of regulated, isolated power at either 5.0 V or 3.3 V
from a 5.0 V input supply, or at 3.3 V from a 3.3 V supply at the
power levels shown in Table 1. These devices eliminate the need
for a separate, isolated dc-to-dc converter in low power, isolated
designs.

APPLICATIONS INFORMATION
The dc-to-dc converter section of the ADuM640x works on
principles that are common to most switching power supplies. It
has a secondary side controller architecture with isolated pulse-
width modulation (PWM) feedback. VDD1 power is supplied to
an oscillating circuit that switches current into a chip scale air
core transformer. Power transferred to the secondary side is
rectified and regulated to either 3.3 V or 5 V. The secondary
(VISO) side controller regulates the output by creating a PWM
control signal that is sent to the primary (VDD1) side by a dedicated
iCoupler data channel. The PWM modulates the oscillator
circuit to control the power being sent to the secondary side.
Feedback allows for significantly higher power and efficiency.
The total lead length between the ends of the low ESR capacitor
and the input power supply pin must not exceed 2 mm. Installing
the bypass capacitor with traces more than 2 mm in length may
result in data corruption. Consider bypassing between Pin 1
and Pin 8 and between Pin 9 and Pin 16 unless both common
ground pins are connected together close to the package.

Figure 27. Recommended PCB Layout
In applications involving high common-mode transients, ensure
that board coupling across the isolation barrier is minimized.
Furthermore, design the board layout such that any coupling that
does occur affects all pins equally on a given component side.
Failure to ensure this can cause voltage differentials between
pins exceeding the absolute maximum ratings for the device
as specified in Table 19, thereby leading to latch-up and/or
permanent damage.
A minimum load current of 10 mA is recommended to ensure
optimum load regulation. Smaller loads can generate excess noise
on chip due to short or erratic PWM pulses. Excess noise that is
generated in this way can cause data corruption, in some cases.
PCB LAYOUT
The ADuM640x digital isolators with 0.4 W isoPower integrated
dc-to-dc converter require no external interface circuitry for the
logic interfaces. Power supply bypassing is required at the input
and output supply pins (see Figure 27). Note that low ESR bypass
capacitors are required between Pin 1 and Pin 2 and between
Pin 15 and Pin 16, as close to the chip pads as possible.
The ADuM640x is a power device that dissipates approximately
1 W of power when fully loaded and running at maximum speed.
Because it is not possible to apply a heat sink to an isolation
device, the device primarily depends on heat dissipation into
the PCB through the GND pins. If the device is used at high
ambient temperatures, provide a thermal path from the GND
pins to the PCB ground plane. The board layout in Figure 27
shows enlarged pads for Pin 8 (GND1) and Pin 9 (GNDISO).
Multiple vias should be implemented from the pad to the ground
plane to significantly reduce the temperature inside the chip.
The dimensions of the expanded pads are at the discretion of
the designer and depend on the available board space.
The power supply section of the ADuM640x uses a 180 MHz
oscillator frequency to pass power efficiently through its chip
scale transformers. In addition, the normal operation of the data
section of the iCoupler introduces switching transients on the
power supply pins. Bypass capacitors are required for several
operating frequencies. Noise suppression requires a low induc-
tance, high frequency capacitor, whereas ripple suppression and
proper regulation require a large value capacitor. These capacitors
are most conveniently connected between Pin 1 and Pin 2 for
START-UP BEHAVIOR
V
DD1, and between Pin 15 and Pin 16 for VISO.
The ADuM640x devices do not contain a soft start circuit.
Therefore, the start-up current and voltage behavior must be
taken into account when designing with this device.
To suppress noise and reduce ripple, a parallel combination of
at least two capacitors is required. The recommended capacitor
values are 0.1 μF and 10 μF for VDD1 and VISO. The smaller
capacitor must have a low ESR; for example, use of a ceramic
capacitor is advised.
When power is applied to VDD1, the input switching circuit begins
to operate and draw current when the UVLO minimum voltage
is reached. The switching circuit drives the maximum available
power to the output until it reaches the regulation voltage where
PWM control begins. The amount of current and the time
required to reach regulation voltage depends on the load and
the VDD1 slew rate.
With a fast VDD1 slew rate (200 μs or less), the peak current draws
up to 100 mA/V of VDD1. The input voltage goes high faster than
the output can turn on, so the peak current is proportional to
the maximum input voltage.
Rev. A | Page 21 of 28
ADuM6400/ADuM6401/ADuM6402/ADuM6403/ADuM6404
Data Sheet
With a slow VDD1 slew rate (in the millisecond range), the input
voltage is not changing quickly when VDD1 reaches the UVLO
minimum voltage. The current surge is approximately 300 mA
because VDD1 is nearly constant at the 2.7 V UVLO voltage. The
behavior during startup is similar to when the device load is a
short circuit; these values are consistent with the short-circuit
current shown in Figure 16.
DC CORRECTNESS AND MAGNETIC FIELD
IMMUNITY
Positive and negative logic transitions at the isolator input
cause narrow (~1 ns) pulses to be sent to the decoder via the
transformer. 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
is 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 unpowered or nonfunctional, and
the isolator output is forced to a default state by the watchdog
timer circuit. This situation should occur in the ADuM640x
devices only during power-up and power-down operations.
When starting the device for VISO = 5 V operation, do not limit
the current available to the VDD1 power pin to less than 300 mA.
The ADuM640x devices may not be able to drive the output to
the regulation point if a current-limiting device clamps the VDD1
voltage during startup. As a result, the ADuM640x devices can
draw large amounts of current at low voltage for extended
periods of time.
The output voltage of the ADuM640x devices exhibits VISO
overshoot during startup. If this overshoot could potentially
damage components attached to VISO, a voltage-limiting device
such as a Zener diode can be used to clamp the voltage. Typical
behavior is shown in Figure 21 and Figure 22.
The limitation on the magnetic field immunity of the ADuM640x
is set by the condition in which induced voltage in the receiving
coil of the transformer is sufficiently large to either falsely set or
reset the decoder. The following analysis defines the conditions
under which this may occur. The 3.3 V operating condition of the
ADuM640x is examined because it represents the most suscept-
ible mode of operation.
EMI CONSIDERATIONS
The dc-to-dc converter section of the ADuM640x devices must
operate at 180 MHz to allow efficient power transfer through the
small transformers. This creates high frequency currents that can
propagate in circuit board ground and power planes, causing
edge emissions and dipole radiation between the primary and
secondary ground planes. Grounded enclosures are recommended
for applications that use these devices. If grounded enclosures
are not possible, follow good RF design practices in the layout
of the PCB. See the AN-0971 Application Note for board layout
recommendations.
The pulses at the transformer output have an amplitude greater
than 1.0 V. The decoder has a sensing threshold at approximately
0.5 V, thus establishing a 0.5 V margin in which induced voltages
can be tolerated. The voltage induced across the receiving coil is
given by

V = (−dβ/dt) ∑ πrn ; n = 1, 2, … , N
where:
β is the magnetic flux density (gauss).
rn is the radius of the nth turn in the receiving coil (cm).
N is the total number of turns in the receiving coil.
PROPAGATION DELAY PARAMETERS
Propagation delay is a parameter that describes the time it takes
a logic signal to propagate through a component. The propagation
delay to a logic low output may differ from the propagation
delay to a logic high output.
Given the geometry of the receiving coil in the ADuM640x 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 29.

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 voltage is approxi-
mately 50% of the sensing threshold and does not cause a faulty
output transition. Similarly, if such an event occurs during a
transmitted pulse (and is of the worst-case polarity), it reduces
the received pulse from >1.0 V to 0.75 V—still well above the
0.5 V sensing threshold of the decoder.

immune and can be affected only by extremely large currents
operated at high frequency very close to the component. For the

The VDD1 power supply input provides power to the iCoupler data
channels as well as to the power converter. For this reason, the
quiescent currents drawn by the data converter and the primary
and secondary input/output channels cannot be determined
separately. All of these quiescent power demands are combined
into the IDD1(Q) current shown in Figure 31. The total IDD1 supply

pulses to the inactive secondary output channels. The outputs

power is established. The primary side oscillator also begins to

CURRENT LIMIT AND THERMAL OVERLOAD
PROTECTION
The secondary VISO voltage is below its UVLO limit at this point;
the regulation control signal from the secondary side is not being
generated. The primary side power oscillator is allowed to free
run under these conditions, supplying the maximum amount of
power to the secondary side.
The ADuM640x is protected against damage due to excessive
power dissipation by thermal overload protection circuits.
Thermal overload protection limits the junction temperature to
a maximum of 150°C (typical). Under extreme conditions (that
is, high ambient temperature and power dissipation), when the
junction temperature starts to rise above 150°C, the PWM is
turned off, turning off the output current. When the junction
temperature drops below 130°C (typical), the PWM turns on
again, restoring the output current to its nominal value.
As the secondary side voltage rises to its regulation setpoint,
a large inrush current transient is present at VDD1. When the
regulation point is reached, the regulation control circuit pro-
duces the regulation control signal that modulates the oscillator
on the primary side. The VDD1 current is then reduced and is
proportional to the load current. The inrush current is less than
the short-circuit current shown in Figure 16. The duration of
the inrush current depends on the VISO loading conditions and
on the current and voltage available at the VDD1 pin.
Consider the case where a hard short from VISO to ground occurs.
At first, the ADuM640x reaches its maximum current, which is
proportional to the voltage applied at VDD1. Power dissipates on
the primary side of the converter (see Figure 16). If self-heating
of the junction becomes great enough to cause its temperature
to rise above 150°C, thermal shutdown is activated, turning off
the PWM and turning off the output current. As the junction
temperature cools and drops below 130°C, the PWM turns on
and power dissipates again on the primary side of the converter,
causing the junction temperature to rise to 150°C again. This
thermal oscillation between 130°C and 150°C causes the part
to cycle on and off as long as the short remains at the output.
As the secondary side converter begins to accept power from
the primary, the VISO voltage starts to rise. When the secondary
side UVLO is reached, the secondary side outputs are initialized
to their default low state until data is received from the corre-
sponding primary side input. It can take up to 1 μs after the
secondary side is initialized for the state of the output to
correlate to the primary side input.
Secondary side inputs sample their state and transmit it to the
primary side. Outputs are valid about 1 μs after the secondary
side becomes active.
Thermal limit protections are intended to protect the device
against accidental overload conditions. For reliable operation,
externally limit device power dissipation to prevent junction
temperatures from exceeding 130°C.
Because the rate of charge of the secondary side power supply is
dependent on loading conditions, the input voltage, and the output
voltage level selected, take care that the design allows the con-
verter sufficient time to stabilize before valid data is required.
POWER CONSIDERATIONS
The ADuM6400/ADuM6401/ADuM6402/ADuM6403/
ADuM6404 power input, data input channels on the primary
side, and data input channels on the secondary side are all
protected from premature operation by undervoltage lockout
(UVLO) circuitry. Below the minimum operating voltage, the
power converter holds its oscillator inactive, and all input channel
drivers and refresh circuits are idle. Outputs remain in a high
impedance state to prevent transmission of undefined states
during power-up and power-down operations.
When power is removed from VDD1, the primary side converter
and coupler shut down when the UVLO level is reached. The
secondary side stops receiving power and starts to discharge.
The outputs on the secondary side hold the last state that they
received from the primary side. Either the UVLO level is reached
and the outputs are placed in their high impedance state, or the
outputs detect a lack of activity from the primary side inputs
and the outputs are set to their default low value before the
secondary power reaches UVLO.

Bipolar ac voltage is the most stringent environment. The goal
of a 50-year operating lifetime under the bipolar ac condition
determines the maximum working voltage recommended by
THERMAL ANALYSIS
The ADuM640x devices consist of four internal silicon die
attached to a split lead frame with two die attach paddles. For
the purposes of thermal analysis, the device is treated as a thermal
unit with the highest junction temperature reflected in the θJA
value from Table 14. The value of θJA is based on measurements
taken with the part mounted on a JEDEC standard 4-layer board
with fine width traces and still air. Under normal operating
conditions, the ADuM640x operates at full load across the full
temperature range without derating the output current. How-
ever, following the recommendations in the PCB Layout section
decreases the thermal resistance to the PCB, allowing increased
thermal margin at high ambient temperatures.
Analog Devices.
In the case of unipolar ac or dc voltage, the stress on the insu-
lation is significantly lower. This allows operation at higher
working voltages while still achieving a 50-year service life.
The working voltages listed in Table 20 can be applied while
maintaining the 50-year minimum lifetime, provided that the
voltage conforms to either the unipolar ac or dc voltage cases.
Any cross-insulation voltage waveform that does not conform
to Figure 33 or Figure 34 should be treated as a bipolar ac wave-
form and its peak voltage limited to the 50-year lifetime voltage
value listed in Table 20. The voltage presented in Figure 33 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.
INSULATION LIFETIME
All insulation structures eventually break down when subjected
to voltage stress over a sufficiently long period. The rate of insu-
lation 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 life-
time of the insulation structure within the ADuM640x devices.

Analog Devices performs accelerated life testing using voltage
levels higher than the rated continuous working voltage. Accel-
eration 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 20 summarize the
peak voltage for 50 years of service life for a bipolar ac operating
condition and the maximum CSA/VDE approved working vol-
tages. 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.

The insulation lifetime of the ADuM640x devices 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 32, Figure 33, and Figure 34 illustrate these
different isolation voltage waveforms.
