TPS2546: TPS2546 Application Question

Wen Yung

Part Number: TPS2546

Hi Sir,

Current we simulate TPS2546 function now, but have some question need you help.

We require if mobile not support CDP and TPS2546 can auto change to SDP. I would appreciate if you can provide test data prove that? since we have no device to verification.

TPS2546 need implement CDP/SDP and DCP two function. note on my system no MCU.

Thanks.

One way to simulate this using a modern phone is to power OFF the phone and then connect to the TPS2546 in CDP mode. This will invoke the CDP-SDP auto switch so you can capture on a scope. Below is a screenshot captured using an LG smart phone with the power OFF.
