(ADuM14x)Datasheet revision change. Rev.I vs Rev.J

Hi !

We detected you change ADuM14x datasheet.

We have to explain to our customer why you change it and what is changed every time.

So I want to confirm some things.

1) What is the difference between "DIN V VDE V 0884-10" and "DIN V VDE V 0884-11"?

Would "DIN V VDE V 0884-11" cover "DIN V VDE V 0884-10"?

2) Why did you add these two parameter to absolute maximum?

Best regards

Kawa

    Hi Kawa, 

    The VDE 0884-10:2006-12 standard was withdrawn several months ago. The standard has been replaced with VDE 0884-11:2017:01. The major change in the standard is the inclusion of high voltage endurance testing. The manufacturer is now required to provide that data at the time of certification.  

    The standard change applies to all digital isolation products with the VDE certification. It's not specific to the ADuM14x family. The most up to date information on all certifications can always be found on the Safety and Regulatory Certification page linked to here and on the first page of every datasheet. 

    The 150C junction temperature remains the limit for fault conditions under 0884-11. Some designs are not required to hold this certification and may wish to restrict available power during a fault to higher levels. In house testing has shown the isolators can tolerate higher junction temps during a fault. 

    Regards,

  • Hi !

    Thank you for your reply.

    Sorry ,I was in vacation.

    I was checking your answer.

    Q1)

    At Figure 6, it is written VDE 0844-10.

    Is it typo?

    VDE 0844-11 is correct?

    Q2)

    I'm not very familiar with insulation standards.

    But was the temperature added to the absolute maximum ratings part because of the change in insulation standards that made it necessary?

    Best regards

  • Hello Kawa

    The certification for the ADuM141 was received recently, it takes a while to update data sheets.  There were about 20 other parts certified at the same time than need updating.  The most up to date certification information is on our web site.  We have about 50 more scheduled to complete this fall.  So it will be keeping the editors busy.

    The change in the abs max table wan not directly connected to the requirements of the new standard, we are adding information for people who need to push the technology.
