Hide,
That is a good question.
Hideyuki Takisawa said:Part Number: ISO5852S-EP
What is the difference ISO5852S-EP and ISO5852S? Do we have any documentation to explain this?
the -EP basically means its "Enhanced Product", they are parts specially offered for defense applications using COTS components, or aerespace or even medical application, which have special requirements for things like package and lead materials, orderable name (starts with V) and other things that. More specifically for the context of this part, it means its is strictly MFRd at one fab, and one package site.
Please see the below Section from TI's EP catalogue which explains the requirements for "-EP" enhanced protection parts, if youre curious. You will see ISO5852S-EP listed in the catalog as well. Below is the excerpt that explains the basic requirements
Internally, the die is exactly the same, so ISO5852S-EP operates exactly same as ISO5852S and the Q1 variant.
If its for a certain defense application, the customer would definitely know if they need to choose the EP part, so no need to worry about it!
I hope this helped to answer your question. Please dont hesitate to let me know if you have more questions!
Best
Dimitri
