Part Number: TPS65987EVM

Hello,

I try to use the GUI tools and the TPS65987EVM for a new prodruct developpement

on the USB-C I always connect a Galaxy S40 smartphone ;

The TPS65987EVM SYS_PWR is connected to a power supply 5V 2A

The goal is when the power supplys is on the Galaxy S40 must be charged (sink mode) , when the power supply swithc off  the S40 must swap to source to power up the board.

Could you welp me to set up the  TPS65987, because since now I was not able to manage this.

Also do you have any documentation about the regiser and command of the TPS65987.

Best regards

David LAURENT

  • Hi David,

    Create a DRP project that prefers Power Source. You can refer http://www.ti.com/lit/ug/slvub60b/slvub60b.pdf for generating project file and http://www.ti.com/lit/ug/slvubh2b/slvubh2b.pdf for details on registers/ Host interface commands.

    Thanks

    Hi Prajith,

    thanhs for you answer. for the document for details on register.

    I made some more test , I use the DRP project Power source.

    but I get some problem .

    The evaluation board is power up by the 20 power supply. I plug the smarphone on the USB-C type . The smartphone charge ( good !) .

    I switch off the 20V power supply the smarphone change mode and become source . but when I plug back the 20 power supply the smartphone didn't charge again.

    In the same time on the debug mode the port configuration is now UFP , and also all the register change see below.

    I change the project example by adding a 0x1 at the customer user word 1, and when I unplug the power supply on the debug mode I read 0x0 in this field !!!

    It is like when swap between source to sink the component reset with another configuration.

    I measure P3V3 you can see the graph below..

    Hi David,

    When the Adapter is removed from the EVM (EVM powered by Smartphone), the PD controller will switch to DeadBattery mode (Register 0x2d:2). PD controller will continue its operation in DeadBattery mode until you clear bootflag by sending DBfg 4CC command(after connecting the Barrel Jack adapter back). 

    Please try the project file attached-  87DDJ_ConsumerProvider.pjt Will there be an EC in your end product to issue 4CC command(DBfg)? 

    Thanks

    Hi Prajith,

    thank you for your help, I'm goign to test right now.

    But I can open or import your project because it is done with GUI6.2 and not for the component TPS65987.

    do you think I can get the last gui and could you manage to change the project for my device ?

    Best regards

    David
