AFE4403: ISO 80601-2-61 / 201.13.101 test issue

Alan Kim

Part Number: AFE4403

For (ISO 80601-2-61) 201.13.101 test "Detection of PROBE FAULTS and PROBE CABLE EXTENDER faults"

I want to ask if there is a pin protection circuit design guide for INN and INP, especially when TXN/TXP and INN/INP are shorted.

Thank you.

Hi,

We are not familiar with the ISO tests and/or standard/regulation.

According to AFE4403 datasheet 8.4.2 Diagnostics, there is short detection.

But there is no short protection.

We don't have design guide for short protection.

Suggestion could be at the path/net where you observe/measure/think unwanted/unexpected high/excessive current could occur, you may add fuse there.

Thanks
