Other Parts Discussed in Thread: TPS65982-EVM, TPS65982

We are developing an aggressive  go to market product based upon these ICs and would like to invite those here who have expertise in these products
to speak with us about a potential collaboration.

We are also looking for people who are versed in the development  USB  PD of driver software for the  Windows and Android markets.


If you think you might be interested in bringing this product to life, please contact me to discuss details.

    Hi Chris,

    Which TPS659xx devices?

    Richard, we are currently working with the TPS65982-EVM, I should have made that clearer

    I have notified the proper person for this device.

    Hi Chris,

    What specific type of product are you developing? Is it a USB Type-C PD charger? Is it a host system (Tablet/Phone/Notebook)? Is it an accessory (dock/dongle)?

    USB Power Delivery (Power/Alternate Mode) should require little to no interaction with the operating system. 

    When USB is established the proper signals are muxed to Type-C port and the host chipset will enumerate the USB device. The same thing happens with the DisplayPort when it is established over USB PD, where the graphics would detect that a monitor has been connected. 

    The TPS65982-EVM allows you to simulate every type of USB Type-C product to verify the cable detect/connection, USB PD communication, and power management. Did you have a chance to look at the various mode that the EVM supports?

    Hey Jacob, thanks for your reply.

    In essense, what we are looking at doing is using the TPS65982 on each usb cable to carry up to 22Vdc  into the batteries which are 3.7V cells ( 5S).

    We are looking for the TPS65982 to faciliate the delivery of power to the cells for trickle charging as well as control the output.

    Basically we want one Type-C connector for each battery pack.

    We have up to 16 packs within container and we envision a USB PD hub/switch device.

    We would like to be able to route power from one device to another and create switched battery cells.

    We may be looking at having the TPS65982 circuitry inside each battery pack, or it may make sense to place all the PD electronics in a hub/switch.

    We anticipate that to fully control all the packs, we would need to make use of the USB spec's System Policy Manager, to control the PD of each TPS65982.

    Our thoughts are to implement this SPM on a discrete microprocessor that would communicate over USB from the root hub.


    Are we mistaken in our approach and is there a better way to do what we want with the TI product?


    Best Regards


    Chris

    Hi Chris,

    In regards to creating/outputing 22Vdc on a USB-C cable, per the USB-C and PD specifications the max voltage that can be transmitted is 20V. If greater than 20Vdc is required, two things are needed: a custom e-marked USB-C cable that is capable of supporting that voltage (and whatever amperage is planned to output across that cable) and a custom Alternate Mode to enable a PDO that is greater than 20Vdc.

    For more information on what is acceptable in the USB-C and PD specifications please refer to the latest specification documents on USB website. If you need anything further clarified about the specifications please let us know.

    Regards,

    Karl
