AMC1300: Magnetic Field Affection

Masayuki Uchihara

Part Number: AMC1300

Hi Team,

I have question about the magnetic field affection of AMC1300.

We can see too much error. The error is over the expectation which are like shunt resistor variant, temperature affection etc...

Do you know any reasons? I guess magnetic interference is one of reason. 

Condition:

Current: Shunt current is 2000A

Magnetic flux density : around 200mT

If you have any question, please let me know.

Thanks,

Uchihara

    Hi Uchihara-san,

    We do not have any device specific information about magnetic immunity for the AMC1300, these tests are normally run at the system level, not at the component level.  What sort of errors (specifically) are you seeing?  The capacitive isolation of the AMC1300 should be immune to magnetic fields, so if you can provide test results, schematic and layout detail of the board you are working with we'd be happy to take a look and see if we see anything.
