TPS3890: Confirmation on two specs in datasheet

Part Number: TPS3890

Here have two specs in our datasheet, and we want to double confirm with you.

  1. About the MR signal low voltage level max value is 0.25VDD, but we see there is 0.3VDD in the sequence picture.

Could you help to confirm whether this is the typo? Or any other consideration?

      2. Whether tMRW 1us should be late after Td(MR)? Or include td(MR)?   You can see in the picture, we could not see the tMRW is longer than 1us. Seems like 250ns.

  • Hello, 

    Thank you for your question. For the first question, that should be a typo and we will fix it in our next revision of the datasheet. For now please use .3*Vdd for your use.

    For the second question I would recommend td(MR) + tMRW for the minimum \MR signal timing.
