ADuM6200/ADuM6201/ADuM6202
For example, at a magnetic field frequency of 1 MHz, the
Data Sheet
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.

The preceding magnetic flux density values correspond to
specific current magnitudes at given distances from the
ADuM620x transformers. Figure 26 expresses these allowable
current magnitudes as a function of frequency for selected
distances. As shown in Figure 26, the ADuM620x is 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 ADuM620x is required to affect the operation of the device.

Figure 27. Power Consumption Within the ADuM620x
Both dynamic input and output current is consumed only
when operating at channel speeds higher than the refresh
rate, f r . 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 I DD1 current to be calculated:

where:
I DD1 is the total supply input current.
I ISO is the current drawn by the secondary side external loads.
E is the power supply efficiency at the maximum load from
Figure 9 at the V ISO and V DD1 condition of interest.
I CHn is the current drawn by a single channel, determined from
Figure 19 or Figure 20, depending on channel direction.

for Various Current-to- ADuM620x Spacings
Note that at combinations of strong magnetic field and high
frequency, any loops formed by PCB traces can induce error
voltages sufficiently large to trigger the thresholds of succeeding
circuitry. Exercise care in the layout of such traces to avoid this
possibility.
POWER CONSUMPTION
The V DD1 power supply input provides power to the i Coupler 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 I DD1(Q) current shown in Figure 27. The total I DD1 supply
current is the sum of the quiescent operating current, the dynamic
current I DD1(D) demanded by the I/O channels, and any external
I ISO load.
where:
I ISO(LOAD) is the current available to supply an external secondary
side load.
I ISO(MAX) is the maximum external secondary side load current
available at V ISO .
I ISO(D)n is the dynamic load current drawn from V ISO by an input
or output channel, as shown in Figure 19 and Figure 20 for a
typical 15 pF load.
This analysis assumes a 15 pF capacitive load on each data output.
If the capacitive load is larger than 15 pF, the additional current
must be included in the analysis of I DD1 and I ISO(LOAD) .
To determine I DD1 in Equation 1, additional primary side
dynamic output current (I AOD ) is added directly to I DD1 .
Additional secondary side dynamic output current (I AOD )
is added to I ISO on a per-channel basis.
