Hi Sirs,

We need use Type A to Type C port.

We don't need support USB3.0/ DP signal and PD function.

Only need USB2.0 signal.

The schematic as below, could you help double confirm again?

Hi,
The TPS25810 schematic seems fine, but I have one question
you said you need USB2.0 signal, do you need CDP or SDP?
CDP is Data+1.5A(max) charging current SDP is data+500mA current
if you need CDP, then recommend TPS2546/TPS2549/TPS254900.

Hi Sirs,

Thanks for your quick reply.

If our end customer applicaiton don't need USB3.0,/PD., and VBus power only support 5V /500mA . When M/B have dual USB2.0 signal, do we need use DFP Controller (TPS25810 ) and USB2.0 Mux/DeMux ?

The function block as below, thanks!!

Hi,

connect two DP1 and DP1 together of TYPE-C connector. connect two DN1 and DN1 together of TYPE-C connector.
then, connect DP to USB+, DM to USB-.
One USB of Chipset is enough.
