Part Number: TPS659039-Q1

i want to select ordering code of TPS659039-Q1
but this chip work with a "firmware" witch change the boot sequence of his output
all docs available speak about only timming sequences of O9039A389IZWSRQ1 / O9039A387IZWSRQ1 / O9039A385IZWSRQ1 variant of ordering code
where did i can find the sequence of the 5 others ordering code available?
8 ordering code actualy is available

    Hi,

    Welcome to E2E! Below are the differences in orderables:

    O9039A385IZWSTQ1 - smaller quantity (250), same device as O9039A385IZWSRQ1
    O9039A387IZWSTQ1 - smaller quantity (250), same device as O9039A387IZWSRQ1
    O9039A389IZWSTQ1 - smaller quantity (250), same device as O9039A389IZWSRQ1

    O9039A344IZWSRQ1 - same sequencing as O9039A385IZWSRQ1, lower voltage on MPU and CORE rails (1.1V, 1.06V)
    O9039A360IZWSRQ1 - same sequencing as O9039A387IZWSRQ1 , lower voltage on MPU and CORE rails (1.1V, 1.06V)
    O9039A36BIZWSRQ1 - same sequencing as O9039A389IZWSRQ1 , lower voltage on MPU and CORE rails (1.1V, 1.06V)

    The bottom three are older devices, I do not recommend these. I suggest choosing out of the first three devices and then deciding if you want the large or small reel (250pc or 1000pc).

    Please let me know if you have additional questions.

    Thanks,

    Thanks for your answer.

    For my application the best choice is O9039A389IZWSTQ1  but  it missing a pre-set 3V3 on any smps.

    what about firmware config of TPS659038?

    O9038A342IZWSRQ1

    O9038A352IZWSRQ1

    I got another question about usage of OTP

    is it a one time programming by bit or register or entire memory?

    Pauzet,

    I recommend you use a load switch with REGEN1 to get the 3.3V. This will also ensure correct sequencing. An example of this setup is in our user guide, which you can find here:

    www.ti.com/.../swcu175b.pdf

    Additionally, the OTP is set for the entire memory during production in our factories.

    Please let me know if you have any other questions.

    Thanks,
    Nastasha
