ADuM1100

Given the geometry of the receiving coil in the ADuM1100 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 8.

Figure 8. Maximum Allowable External Magnetic Field
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 will 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 ADuM1100
transformers. Figure 9 expresses these allowable current magnitudes
as a function of frequency for selected distances. As can be seen,
the ADuM1100 is extremely 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 current of 0.5 kA 5 mm away from the
ADuM1100 to affect the component’s operation.

Figure 9. Maximum Allowable Current for
Various Current-to-ADuM1100 Spacings
Note that at combinations of strong magnetic field and high
frequency, any loops formed by printed circuit board traces could
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.
