Part Number: UCC2801-EP

Hello,

I am using the UCC2801QDREP for one of my designs and I want to change it by the UCC2801MDREP. The only difference seen between the two versions is the temperaure range, -40 to 125°C for UCC2801QDREP and -55 to 125°C for UCC2801MDREP.

I would like to know :

Except for the temperature holding, what do we get for the UCC2801MDREP compared to the UCC2801QDREP version ?
Has the UCC2801MDREP version been specifically tested?
As for the UCC2801MDREP version, I would like to know if the UCC2801QDREP has been qualified at -55°C to 125°C.

The aim is to identify differences between the UCC2801QDREP and UCC2801MDREP.

Thank you for your support.

Best regards.

Hi Moha,

The part number difference Q and M is the temperature range indicator. Nothing else is different between UCC2801QDREP & UCC2801MDREP.

UCC2801QDREP & UCC2801MDREP are the same die and had undergone the same test process of -55C, 25C, and 125C. So you are able to stress UCC2801QDREP to -55C.

Best,

Claire

Hi Claire,

Thank you for your answer.

I made a verification on your qualification summary and was a little supprised that we do not have any difference between the performed tests on UCC2801QDREP & UCC2801MDREP versions.

If both versions had the same tests. What will we get if we use the UCC2801MDREP instead of the UCC2801QDREP version ? Nothing ?

If both undergo the same tests, whay do you have two versions with two different temperature ranges ? As you said there is no difference between the two versions.

Why am I asking you these questions is that the UCC2801QDREP is breaking unjustly, we though that the temperature was causing a stress. But your answer and my searchs require us to review our reflection because both versions undergo the same tests.

Thank you for your support.

Best regards,

Moha

Hi Moha,

I am not sure why TI did this, this part is very old and has a long history that I cannot trace back to whom to reach out to. But I can ensure you that the data I have provided is accurate and that both parts can be stressed to -55C. I have answered your initial question and therefore I will close this thread. If there are any other questions, feel free to submit another E2e thread.

Thanks,

Claire
