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.
ThanksPrajith

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..

Thank you very much
In reply to david Laurent:
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

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 ?
