Other Parts Discussed in Thread: TPS65982

Hi,

I use a TPS65982 on my board to sink power from battery device with PD function,There are 2 options: low region binary file or full flash binary file. What`s the difference?I want to programe the bin file to SPI flash,and automatic Initialize TPS65982

    Hi Yang,

    I would recommend using the Full-Flash binary file since that contains both the low region and high region application code. Section 3.5 of the Firmware User's Guide highlights the differences between the various regions stored in the external Spi-flash.
    Here is a link to the Firmware User's Guide: www.ti.com/.../slvuah7b.pdf

    Thank you,
    Eric

    hi Eric ,Thank you so much！Still  have 2 questions.

    I used the reference circuit design on my board(ver A) and used the default Project in the tool to generate the bin file , it actually worked. The voltage sinked from the battery device is about 15V(18W). Now I want to save the external MOS  CSD8750, the power should go through the PPHV channel in stead of EXT mos , but it cannot work. I am not sure  how to setup PP_5V0 configuration, PP_HV configuration, PP_EXT configuration in the tool,should it be input or output?

    The numbers of sink PDOs is defaut 2.It seems go to 5V(can`t be changed) then accend to next level about 15V on my board. However I designed a battery protection circuit on the board(ver B), the DC/DC will not work while input<10.5V.should it be a problem?is there any solution?

    thank you,

    Yang

    Hi Yang,

    Are you using the TPS65982EVM?

    Thank you,

    Hi Eric,

    I use the <TPS65982EVM user`s guide> as reference, almost copy the TPS65982 part of schematics. I don`t have the EVM board.

    Is the EXT NMOS necessary?How to choose the internal path?

    thank you!

    Hi Yang,

    It is not required to use the external NMOS. You can configure how the power paths are used with the TPS6598x Application Customization Tool. You can download it from the following link: www.ti.com/.../tps6598x-config
    You can change the power path settings in the System Configuration Register (0x28).

    Thank you,
    Eric
