Part Number: TUSB4020BI-Q1
Other Parts Discussed in Thread: TPS55289, TPS25772-Q1,

Hi Team,

Project: Automotive PD USB Charger&Hub:

With 2 ports for output, one is a charge only port and another one is a charge + communication port.

The overall scheme currently in use is TPS25772-Q1+TPS55289+TUSB4020BI-Q1 which requires PD power allocation.

Here is the schematic with a description of the PCB Layout and spec:

Requirements: Configure the product function outputs (charging and communication) and disable the communication function of the J2 port to maintain the charging function only.

Could you help check how to configure it? Thanks.

Best Regards,

Cherry

Cherry:

For hub , it only support BC1.2. if more charging function needed, you need to use TPS25772 for charging port, but it may not support data communication.

I will transfer ticket to PI team to see how to support charging and data for the same port.
