Part Number: TPS65988DJEVM
Other Parts Discussed in Thread: TPS65988DJ, TPS25751, TPS25730

Tool/software:

I want to add this part to a design; any chance I can get the layout files and schematic files for easier import into my design?

    Hi Richard,

    The TPS65988DJ is not recommended for new designs. It is also only recommended for use when users are using a specific 3rd part reference design that calls for the specific part.

    What are you port requirements for type-C? We may be able to suggest a different part for your use here if you are not following said reference design.

    Thanks and Regards,

    Chris

    Chris,

    We are helping a customer improve on their design.  They have a tablet that is built into a enclosure with a circuit.  There are 2 USB C's on this board.  One is internal and connects to the tablet.  One is external.  If nothing is connected to the external port the tablet will power the circuit.  If a source is plugged into the external port, it will power the circuit and charge the tablet.

    This is what we are trying to do.  We bought an eval kit for the part mentioned and it seems to work.

    What do you suggest.

    Also, Do you have to have the TIVA to program this chip?

    Hi Richard,

    It sounds like they need power only, one port needing to source and sink (p1), and the other needing to be sink only(p2)?

    The TPS65987Dx family of devices are not recommended for new designs due to limited support going forwards, and them being non-compliant with the latest version of the PD spec.

    These devices are not being End of Life'd, and are compliant with older version of the spec, but you would have to use them at your own risk.

    If using the TPS65987Dx family, you should only be using the TPS65987DK variant at this time.

    For newer parts that meet the requirements stated above, see below:

    P1: Source and Sink. If just for a tablet, you likely only need 5V source and 5-9V sink. The TPS25751 should be a good fit here.

    P2: Sink only. The TPS25730 may be a good fit here as it is a sink only PD controller. If you need additional features and controls, you may need to move to the TPS25751 as well. This device is configurable through a GUI generated binary image loaded on power up. The configuration gives users additional controls.

    Depending on the device you decide to use, I can send you the corresponding EVM files.

    No, we do not share the TIVA fw that is on the EVM. The Tiva is specifically meant for EVM + GUI usage, and not intended for customer implementation. It primarily writes the binary image to the on board SPI Flash (or I2C EEPROM for the TPS25751) and does some basic I2C read and writes to PD controller registers.

    Thanks and Regards,

    Chris
