... V watchdog timer circuit The magnetic field immunity of the ADuM1310 is determined by CTRL GND the changing magnetic field which induces a voltage in the trans- 2 former’s receiving coil large enough to either falsely set or reset the decoder. The following analysis defines the conditions under which this can occur. The ADuM1310’ ...

... Given the geometry of the receiving coil in the ADuM1310 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 at a given frequency can be calculated. The result is shown in Figure 11. 100 0.01 0.001 1k 10k 100k 1M MAGNETIC FIELD FREQUENCY (Hz) Figure 11 ...

... ADuM1310 POWER-UP/POWER-DOWN CONSIDERATIONS Given that the ADuM1310 has separate supplies on either side of the isolation barrier, the power-up and power-down characteristics relative to each supply voltage need to be considered individually. As shown in Table 9, when V input power is off, the DD1 ADuM1310 outputs take on a default condition as determined by the state of the CTRL pin ...
