UCC2813-0: Difference from UCC3813-0

Part Number: UCC2813-0
Other Parts Discussed in Thread: UCC3813-0,

Dear, Sir.

My customer is considering to replace from UCC3813DTR-0 to UCC2813DTR-0,

also from UCC3813DTR-1 to UCC2813DTR-1.

I tried to read out the datasheet, but following are not clear.

Sorry to disturb your job about this kind of matter, Please give your advice.

1) What is the difference between UCC3813DTR-0 & UCC2813DTR-0,

   also UCC3813DTR-1 & UCC2813DTR-1?

2) I wonder same process is applied to UCC3813DTR-0 & UCC2813DTR-0,

   also UCC3813DTR-1 & UCC2813DTR-1?

3) Please give your advice if you have a concern or remarkable point

   for the replacement from UCC3813 to UCC2813.

Best Regards,

H.Sakai

  • Hello H.Sakai,

    The only difference between these parts is the temperature ratings.

    Section 7.5 of the data sheet shows this:

    The UCC3813-0 has a temp range from 0 to 70C and the UCC2813-0 has a temp range from -40C to 85C

    Regards

  • Dear, John-san. 

    Thank you so much for your reply. 

    I would like to double-confirm.

    I wonder the same BiCMOS process is used for both UCC3813-x & UCC2813-x?

    Sorry to ask about this kind of matter, Because the customer's internal authorization

    for new device will become simplified if it was same. 

    Please give your advice one more time. 

    Best Regards, 

    H. Sakai

  • Hi Sakai-san,

    Yes the UCC3813-x and the UCC2813-x are manufactured with the same process.

    The only difference is the rated temperature range.

    Regards

  • Dear, John-san. 

    I appreciate all of your valuable information. 

    Regarding testing process, I wonder the testing for UCC2813-x & UCC3813-x are 

    totally separated? 

    OR the base of testing is for UCC3813-x, so additional testing(such as screening) is added 

    for UCC2813-x for wide temperature range assurance product? 

    Sorry to disturb your job again & again. The customer's question will be last on this. 

    Please give your advice one more time. 

    Best Regards, 

    H. Sakai

  • Hi Sakai-san,

    The tests are all the same and are detailed on the tables of the data sheet. No extra screening or additional testing between parts.

    The only difference is the temperature range that the parts are tested at.

    Regards

    John
