Part Number: TIDA-00987
My application requires charging a cellular phone (based on Android and type C connector) while a USB3 device is connected and communicating with the phone.
Unfortunately, the battery dies after 1-2 hr of work and I need to keep it alive for night tests.
I'm using Type C to uB cable.
The introduction chapter in TIDA-00987 datasheet states: "Texas Instruments Jacinto 6 family processors (DRA7x) allowing simultaneous charge and on-the-go functionality".
Will this board work with my application?

Thank you, Hope, for replying.
Can I buy this board from TI?
In reply to Shlomi Shamam:
TI Designs allow people to find reference material leveraging the best in TI technology – from embedded processors to analog signal chain and power management.
All TI Designs include a schematic, test data and design files however there is no stock for these boards. Feel free to download the TIDA-00987 design files to help accelerate your design process today!
I work with Shlomi on this project and I would like to make sure there are no misunderstanding with regards to desired functionality of this board...
Below attached a block diagram of the desired system.
We would like to charge the phone, at the same time as it is functioning as USB Host (OTG) .
Does TIDA-00987 support such scenario?
If yes, could you please elaborate how the phone is set to sink current , rather than source (as it's expected from Host)?
In reply to David Dobrin:
I'd appreciate if you help us to clarify by answering David's question.
Because the USB switch is integrated into the TPS25810-Q1 Type-C controller, and the data lines are passing through the TPS254900-Q1 BC1.2 controller and the HD3SS3212 bidirectional MUX. For OTG, the BC1.2 controller needs to be configured handle the OTG functionality. For reference, passthrough mode can be done as specified of Section 8.4 (page 23) of the TPS254900-Q1 datasheet.
