TPS3840-Q1: Changes from Revision A (September 2019) to Revision B

Part Number: TPS3840-Q1

Hi support team,
I have a question about Revision History of SNVSBA1B.

The following changes cannot be confirmed in Revision A and Revision B.

Is it a change from Original to Revision A?


  • HI Dice-K,

    The revision history details the changes that were done to the datasheet.  For the TPS3840-Q1, the datasheet went through several revisions.  Can you please clarify what is the question?  The changes to the datasheet from Rev A to Rev B is listed in the picture that you provided.


  • Hi Ben,
    Thank you for your reply.

    From A to B, the changes shown in the attached figure are not found.
    However, it seems that it has changed between the original and A.
    Is the missing of the revision history from the original to A written in the revision history of Revision B as a follow-up?

    Best regards,

  • Hi Dice-K, 

    Looking at our records, the changes from A to B were the hyperlinks in section 2 of Applications and the in section 5 of Device Comparison.  Let me know if you have any more questions.
