ADuM1300/ADuM1301

Data Sheet

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 has 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.

POWER CONSUMPTION

The supply current at a given channel of the ADuM1300/

ADuM1301 isolator is a function of the supply voltage, the data

rate of the channel, and the output load of the channel.

For each input channel, the supply current is given by

I_DDI= I_{DDI (Q)}

f ≤ 0.5 f_r

f > 0.5 f_r

I_DDI= I_{DDI (D)}× (2f − f_r) + I_{DDI (Q)}

The preceding magnetic flux density values correspond to

specific current magnitudes at given distances from the

ADuM1300/ADuM1301 transformers. Figure 17 shows these

allowable current magnitudes as a function of frequency for

selected distances. The ADuM1300/ADuM1301 is extremely

immune and can be affected only by extremely large currents

operated at a high frequency 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 ADuM1300/ADuM1301 to affect

the operation of the component.

For each output channel, the supply current is given by

_DDO= I_{DDO (Q)}

f ≤ 0.5 f_r

_DDO= (I_{DDO (D)}+ (0.5 × 10⁻³) × C_L× V_DDO) × (2f − f_r) + I_{DDO (Q)}

f > 0.5 f_r

where:

I_{DDI (D)}, I_{DDO (D)}are the input and output dynamic supply currents

per channel (mA/Mbps).

C_Lis the output load capacitance (pF).

_DDOis the output supply voltage (V).

1000

f is the input logic signal frequency (MHz); it is half of the input

data rate expressed in units of Mbps.

f_ris the input stage refresh rate (Mbps).

DISTANCE = 1m

100

I_{DDI (Q)}, I_{DDO (Q)}are the specified input and output quiescent

supply currents (mA).

To calculate the total V_DD1and V_DD2supply current, the supply

currents for each input and output channel corresponding to

DISTANCE = 100mm

V_DD1and V_DD2are calculated and totaled. Figure 6 and Figure 7

DISTANCE = 5mm

provide per-channel supply currents as a function of data rate

for an unloaded output condition. Figure 8 provides per-channel

supply current as a function of data rate for a 15 pF output

condition. Figure 9 through Figure 12 provide total V_DD1and

V_DD2supply current as a function of data rate for ADuM1300/

ADuM1301 channel configurations.

for Various Current-to-ADuM1300/ADuM1301 Spacings

Note that at combinations of strong magnetic field and high

frequency, any loops formed by printed circuit board traces

could induce error voltages sufficiently large enough to trigger

the thresholds of succeeding circuitry. Take care in the layout of

such traces to avoid this possibility.
