Hello sir,

Do you have TPS6593-Q1 calculation tool for us to design? BTW, Could you show me the difference between TPS6593-Q1 and TPS6594-Q1 from hardware/software/price/feature and so on aspects?

    Hello Xin,

    performance wise in terms of converters the devices are the same and the datasheets will reflect this. The only significant difference in terms of power handling are the features added to TPS6594 over TPS6593, as TPS6594 can target upto ASIL-D, while TPS6593 targets ASIL-B systems.

    TPS6594 has residual voltage checking on power rails, safety FET to cut power incase of overvoltage on the input side of the chip, etc..

    Overall very similar, difference is what ASIL rating is being targeted for the End Equipment. Is there a targeted System on Chip in mind, we already have solutions to such?

    BR,

    Hello sir,

    thanks for your reply. This part is used to Horizon J6M power supplier which is provided by TI, we have discussing recently this solution. J6M AON/MCU domain is ASIL-D, MAIN domain is ASIL-B.

    By the way, do you have power calculation tool such as TPS6594x-Q1 efficiency estimator tool or other calculation tool? So that we can evaluate the this part details .

    The power calculator tool is what recommend, as the same BUCKs & LDOs are used in the TPS6593, so you can use the calculator with the TPS6594

    selection.

    Do you have any other questions, if not, you can hit resolved? 

    Also you can always return to the thread after clicking resolve to ask a follow up question.
