TLC5926: Error Code Definition

Part Number: TLC5926

Hello,

I couldn't find any information about how to interpret the error code in the datasheet. Is there maybe an additional paper?

Many thanks

    Hi,

    The Error Detection mode is explained in datasheet.

    The timing diagram for the code is showed in figure 8 - figure 10 and so on.

    You can refer to the timing for the reference code to switch to special mode and read error status.

    If you think this answers your question, please help to click "Resolve".

    Thanks.
    Regards,

    Hi Kenneth,

    There ist only described HOW TO READ the error code but unfortunatelly not how many bits it is and how to interpret the bits.

    So I your answer does not what I was looking for.

    Maybe you can provide some more information.

    Thanks

    Sascha

    Hi, Sascha,

    As you can see from the datasheet 9.4.3.1, "the data input source of the Shift Register changes to the 16-bit parallel Error Status Code register", which means the error will load to Error Status Code register, and the 16 bit error register is shown in figure13 from BIT15 to BIT0, which indicates the error code for OUT15 to OUT0:

    You can find ERROR STATUS CODE meaning in 9.3 Feature Description.

    For example, if BIT0 for OUT0 error status is 0, and OUT0 is ON, and VOUT ≥ VOUT,TTh, from table 2, short circuit happens in OUT0.

    Please let me know if this solves your problem.

    Thanks.

    Regards,

    Kenneth
