GENERAL DESCRIPTION
The ADuM5200W/ADuM5201W/ADuM5202W1 are dual-
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 500 mW of
regulated, isolated power at either 5.0 V or 3.3 V from a 5.0 V input
supply, or 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. The iCoupler
chip-scale transformer technology is used to isolate the logic
signals and for the magnetic components of the dc-to-dc
converter. The result is a small form factor, total isolation
solution.
The ADuM5200W/ADuM5201W/ADuM5202W isolators
provide two independent isolation channels in a variety of channel
configurations and data rates (see the Ordering Guide for more
information).
isoPower uses high frequency switching elements to transfer power
through its transformer. Special care must be taken during printed
circuit board (PCB) layout to meet emissions standards. See the
AN-0971 Application Note for board layout recommendations.

TERMINOLOGY
IDD1 (Q)
IDD1(Q) is the minimum operating current drawn at the VDD1 pin
when there is no external load at VISO and the I/O pins are
operating below 2 Mbps, requiring no additional dynamic supply
current. IDD1(Q) reflects the minimum current operating condition.
IDD1 (D)
IDD1 (D) is the typical input supply current with all channels
simultaneously driven at a maximum data rate of 25 Mbps with
full capacitive load representing the maximum dynamic load
conditions. Resistive loads on the outputs should be treated
separately from the dynamic load.
IDD1 (MAX)
IDD1 (MAX) is the input current under full dynamic and VISO load
conditions.
ISO (LOAD)
ISO (LOAD) is the current available to the load.
tPHL Propagation Delay
tPHL propagation delay is measured from the 50% level of the
falling edge of the VIx signal to the 50% level of the falling edge
of the VOx signal.
tPLH Propagation Delay
tPLH propagation delay is measured from the 50% level of the rising
edge of the VIx signal to the 50% level of the rising edge of the
VOx signal.
Propagation Delay Skew, tPSK
tPSK is the magnitude of the worst-case difference in tPHL and/or tPLH
that is measured between units at the same operating temperature,
supply voltages, and output load within the recommended
operating conditions.
Channel-to-Channel Matching, tPSKCD/tPSKOD
Channel-to-channel matching is the absolute value of the
difference in propagation delays between the two channels
when operated with identical loads.
Minimum Pulse Width
The minimum pulse width is the shortest pulse width at which
the specified pulse width distortion is guaranteed.
Maximum Data Rate
The maximum data rate is the fastest data rate at which the
specified pulse width distortion is guaranteed.

APPLICATIONS INFORMATION
The dc-to-dc converter section of the ADuM5200W/
ADuM5201W/ADuM5202W 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 ADuM5200W/ADuM5201W/ADuM5202W implements
undervoltage lockout (UVLO) with hysteresis on the VDD1 power
input. This feature ensures that the converter does not enter
oscillation due to noisy input power or slow power on ramp rates.
The ADuM5200W/ADuM5201W/ADuM5202W can accept an
external regulation control signal (RCIN) that can be connected to
other isoPower devices. This allows a single regulator to control
multiple power modules without contention. When accepting
control from a master power module, the VISO pins can be
connected together adding their power. Because there is only one
feedback control path, the supplies work together seamlessly.
The ADuM5200W/ADuM5201W/ADuM5202W can only
regulate themselves or accept regulation (slave device) from
another device in this product line; they cannot provide a
regulation signal to other devices.
PCB LAYOUT
The ADuM5200W/ADuM5201W/ADuM5202W digital isolators
with 0.5 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 23). 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 power supply section of the ADuM5200W/ADuM5201W/
ADuM5202W 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 inductance, 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 VDD1 and between Pin 15 and Pin 16 for VISO.
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. The smaller capacitor must
have a low ESR; for example, use of a ceramic capacitor is advised.
Note that 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 23. 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
(specified in Table 19.) thereby leading to latch-up and/or
permanent damage.
The ADuM5200W/ADuM5201W/ADuM5202W 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 23 shows enlarged pads for Pin 2, Pin 8,
Pin 9, and Pin 15. 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.

START-UP BEHAVIOR
The ADuM5200W/ADuM5201W/ADuM5202W do not contain
a soft start circuit. Take the startup current and voltage behavior
into account when designing with this device.
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 time this
takes depends on the load and the VDD1 slew rate.
Fast slew-rates, in the 200 µs or smaller range, allow 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.
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 12.
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 ADuM5200W/ADuM5201W/ADuM5202W 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 ADuM5200W/ADuM5201W/ADuM5202W devices
can draw large amounts of current at low voltage for extended
periods of time.
The output voltage of the ADuM5200W/ADuM5201W/
ADuM5202W exhibits VISO overshoot during startup. If this
could potentially damage components attached to VISO, then a
voltage-limiting device, such as a Zener diode, can be used to
clamp the voltage. Typical behavior is shown in Figure 17 and
Figure 18.
EMI CONSIDERATIONS
The dc-to-dc converter section of the ADuM5200W/
ADuM5201W/ADuM5202W 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.
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.

Pulse width distortion is the maximum difference between
these two propagation delay values and is an indication of how
accurately timing of the input signal is preserved.
Channel-to-channel matching refers to the maximum amount
the propagation delay differs between channels within a single
ADuM5200W/ADuM5201W/ADuM5202W component.
Propagation delay skew refers to the maximum amount the
propagation delay differs between multiple ADuM5200W/
ADuM5201W/ADuM5202W components operating 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 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 are sent to
ensure dc correctness at the output. If the decoder receives no
internal pulses of more than about 5 µs, the input side is assumed
to be unpowered or nonfunctional, in which case the isolator
output is forced to a default state (see Table 24) by the watchdog
timer circuit.
The limitation on the magnetic field immunity of the
ADuM5200W/ADuM5201W/ADuM5202W 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 V operating condition of the ADuM5200W/
ADuM5201W/ADuM5202W is examined because it represents
the most susceptible mode of operation.
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, 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
2; n = 1, 2, … , N
where:
β is the magnetic flux density (gauss).
N is the number of turns in the receiving coil.
rn is the radius of the nth turn in the receiving coil (cm).

Rev. 0 | Page 21 of 28
Given the geometry of the receiving coil in the ADuM5200W/
ADuM5201W/ADuM5202W 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 25.

Figure 25. 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 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.
The preceding magnetic flux density values correspond to specific
current magnitudes at given distances from the ADuM5200W/
ADuM5201W/ADuM5202W transformers. Figure 26 expresses
these allowable current magnitudes as a function of frequency for
selected distances. As shown, the ADuM5200W/ADuM5201W/
ADuM5202W are extremely immune and can be affected only by
extremely large currents operated at high frequency very close
to the component. For the 1 MHz example noted, a 0.5 kA
current placed 5 mm away from the ADuM5200W/ADuM5201W/
ADuM5202W is required to affect the operation of the component.

voltages sufficiently large enough to trigger the thresholds of

to avoid this possibility.
POWER CONSUMPTION
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 have been
combined into the IDD1(Q) current shown in Figure 27. The total
IDD1 supply current is the sum of the quiescent operating current,
dynamic current IDD1(D) demanded by the I/O channels, and any
external IISO load.

Figure 27. Power Consumption Within the ADuM5200W/
ADuM5201W/ADuM5202W
Both dynamic input and output current is consumed only when
operating at channel speeds higher than the rate of fr. Because
each channel has a dynamic current determined by its data rate,
Figure 19 shows the current for a channel in the forward direction,
which means that the input is on the primary side of the part.
Figure 20 shows the current for a channel in the reverse direction,
which means that the input is on the secondary side of the part.
Both figures assume a typical 15 pF load. The following
relationship allows the total IDD1 current to be calculated:
IDD1 = (IISO × VISO)/(E × VDD1) + ∑ ICHn; n = 1 to 4 (1)
where :
IDD1 is the total supply input current.
ICHn is the current drawn by a single channel determined from
Figure 19 or Figure 20, depending on channel direction.
IISO is the current drawn by the secondary side external loads.
E is the power supply efficiency at 100 mA load from Figure 9 at
the VISO and VDD1 condition of interest.
ADuM5200W/ADuM5201W/ADuM5202W Automotive Products

Calculate the maximum external load by subtracting the dynamic
output load from the maximum allowable load.
IISO (LOAD) = IISO (MAX) − ∑ IISO(D)n; n = 1 to 4 (2)
where:
IISO (LOAD) is the current available to supply an external secondary
side load.
IISO (MAX) is the maximum external secondary side load current
available at VISO.
IISO(D)n is the dynamic load current drawn from VISO by an input
or output channel, as shown in Figure 19 and Figure 20. Data is
presented assuming a typical 15 pF load
The preceding analysis assumes a 15 pF capacitive load on each
data output. If the capacitive load is larger than 15 pF, the addi-
tional current must be included in the analysis of IDD1 and IISO (LOAD).
To determine IDD1 in Equation 1, additional primary side dynamic
output current (IAOD) is added directly to IDD1. Additional secondary
side dynamic output current (IAOD) is added to IISO on a per
channel basis.
To determine IISO (LOAD) in Equation 2, additional secondary side
output current (IAOD) is subtracted from IISO (MAX) on a per
channel basis.
For each output channel with CL greater than 15 pF, the additional
capacitive supply current is given by
IAOD = 0.5 × 10−3 × (CL − 15) × VISO) × (2f − fr) f > 0.5 fr (3)
where:
CL is the output load capacitance (pF).
VISO is the output supply voltage (V).
f is the input logic signal frequency (MHz); it is half of the input
data rate expressed in units of Mbps.
fr is the input channel refresh rate (Mbps).
CURRENT LIMIT AND THERMAL OVERLOAD
PROTECTION
The ADuM5200W/ADuM5201W/ADuM5202W are 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, reducing the output current to
zero. When the junction temperature drops below 130°C (typical),
the PWM turns on again, restoring the output current to its
nominal value.
Consider the case where a hard short from VISO to ground occurs.
At first, the ADuM5200W/ADuM5201W/ADuM5202W reach
their maximum current, which is proportional to the voltage
applied at VDD1. Power dissipates on the primary side of the
converter (see Figure 12). If self-heating of the junction becomes
great enough to cause its temperature to rise above 150°C, thermal
shutdown activates, turning off the PWM, and reducing the
output current to zero. 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.
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.
POWER CONSIDERATIONS
The ADuM5200W/ADuM5201W/ADuM5202W power input,
data input channels on the primary side and data input channels on
the secondary side are all protected from premature operation
by 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.
During application of power to VDD1, the primary side circuitry
is held idle until the UVLO preset voltage is reached. At that
time, the data channels initialize to their default low output
state until they receive data pulses from the secondary side.
When the primary side is above the UVLO threshold, the data
input channels sample their inputs and begin sending encoded
pulses to the inactive secondary output channels. The outputs
on the primary side remain in their default low state because no
data comes from the secondary side inputs until secondary power
is established. The primary side oscillator also begins to operate,
transferring power to the secondary power circuits. The secondary
VISO voltage is below its UVLO limit at this point; the regulation
control signal from the secondary is not being generated. The
primary side power oscillator is allowed to free run in this
circumstance, supplying the maximum amount of power to
the secondary, until the secondary voltage rises to its regulation
setpoint. This creates a large inrush current transient at VDD1.
When the regulation point is reached, the regulation control
circuit produces the regulation control signal that modulates
the oscillator on the primary side. The VDD1 current is reduced
and is then proportional to the load current. The inrush current
is less than the short-circuit current shown in Figure 12. The
duration of the inrush depends on the VISO loading conditions
and the current available at the VDD1 pin.
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 corresponding
primary side input. It can take up to 1 µs after the secondary
side is initialized for the state of the output to correlate with 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.
Automotive Products ADuM5200W/ADuM5201W/ADuM5202W
Rev. 0 | Page 23 of 28
Because the rate of charge of the secondary side power supply is
dependent on loading conditions and the input voltage level and the
output voltage level selected, take care with the design to allow the
converter sufficient time to stabilize before valid data is required.
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.
THERMAL ANALYSIS
The ADuM5200W/ADuM5201W/ADuM5202W consist of four
internal die, attached to a split lead frame with two die attach
paddles. For the purposes of thermal analysis, it is treated as a
thermal unit with the highest junction temperature reflected in the
θJA 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 ADuM5200W/ADuM5201W/ADuM5202W operate at full
load across the full temperature range without derating the
output current. However, following the recommendations in the
PCB Layout section decreases the thermal resistance to the PCB
allowing increased thermal margin at high ambient temperatures.
INCREASING AVAILABLE POWER
The ADuM5200W/ADuM5201W/ADuM5202W are designed
with the capability of running in combination with other
compatible isoPower devices. The RCIN and RCSEL pins allow the
ADuM5200W/ADuM5201W/ADuM5202W to receive a PWM
signal from another device through the RCIN pin and act as a
slave to that control signal. The RCSEL pin chooses whether the
part acts as a stand-alone self-regulated device or a slave device.
When the ADuM5200W/ADuM5201W/ADuM5202W act as a
slave, their power is regulated by a PWM signal coming from a
master device. This allows multiple isoPower parts to be combined
in parallel while sharing the load equally. When the ADuM5200W/
ADuM5201W/ADuM5202W are configured as standalone units,
they generate their own PWM feedback signal to regulate
themselves.
The ADuM5000 can act as a master or a slave device, the
ADuM5401, ADuM5402, ADuM5403, and ADuM5404 can
only be master/ standalone, and the ADuM520x can only be
a slave/standalone device. This means that the ADuM5000,
ADuM520x, and ADuM5401 to ADuM5404 can only be used
in certain master/ slave combinations as listed in Table 25.

INSULATION LIFETIME
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 ADuM5200W/
ADuM5201W/ADuM5202W.
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 20 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 a 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 ADuM5200W/ADuM5201W/
ADuM5202W 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 28, Figure 29, and Figure 30
illustrate these different isolation voltage waveforms.
Bipolar ac voltage is the most stringent environment. The goal
of a 50-year operating lifetime under the ac bipolar condition
determines the maximum working voltage recommended by
Analog Devices.
In the case of unipolar ac or dc voltage, the stress on the insula-
tion 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 the voltage conforms to
either the unipolar ac or dc voltage cases. Any cross insulation
voltage waveform that does not conform to Figure 29 or Figure 30
should be treated as a bipolar ac waveform and its peak voltage
limited to the 50-year lifetime voltage value listed in Table 20.
The voltage presented in Figure 29 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.
