Part Number: ISO7741
Hi allI want to know that after the ISO7741 isolation failure, is the IC IO output disconnected or short circuited? What is the detailed principle.I have seen the ADI brand ADuM261N, ADuM262N, their magnetic isolating chip failure model is open.
The failure mode will always depend on the type of stress applied to the device and ADI will also be similar to TI in this aspect.
Please refer to Understanding Failure Modes. This whitepaper explains in detail the phenomenon behind the cause of failure open in TI isolators and also discusses in detail the different failure modes that can occur at a system level and how they can be avoided.
Hope this helps answer your questions. Let me know if this is sufficient or if any additional data is required.Thanks.
