AMC1304M25: About safety limiting value

Satoshi
Guru 19495 points
Part Number: AMC1304M25

AMC1304 datasheet Page-7 is described about safety limiting value.

Although care about no exceed safety limit, I think that input circuit have difficult case for safety condition.

Please let me know about two points below;

①Is there reference circuit for prevent to exceed safety limit? (Especially I want to see input side) 

②Is there any test data in the case of exceed safety limit?

　For example, whether isolation barrier is break (damage) or not. 

Best regards,

Satoshi

    Hi Satoshi,

    Section 7.8 refers to thermal conditions that can cause damage to the AMC1304M25. I don't have any specific reference circuit to share other than perhaps a fuse. What sort of test data are you looking for? Any current or overall power consumption that exceeds the limits shown in figures 3 and 4 could potentially damage the isolation barrier.
