Part Number: TPS2546

Hi,

Customer reported the issue that TPS2546 cannot charge to the cell phone SONY Xperia Z5 Premium under the DCP_Auto(0111) mode but the same test method with the other cell phone ASUS(Zenfone Go (Z00VD)), Apple iPhone6s and HTC(One e9 plus) did not have this issue. Attached are the schematic and captured waveforms in some tests. Any idea to fix the issue that TPS2546 cannot charge to the cell phone SONY Xperia Z5 Premium under the DCP_Auto(0111) mode as showed #2 in the attached file? Thank you.

can you please provide scope shot with D+ D- when the issue occurs. VBUS, D+, D-, ILIM_SEL at a min. Any other channels that would be helpful but please include D+ and D-. The SONY Xperia may use a different charging scheme. BC1.2, Divider1/2, or 1.2C Charging scheme.
Please also include the same captures with D+ and D- in the working cases.

Hi Randy,

Since there hasn't been any activity over the last 2 weeks, I'm going to close this thread. Please feel free to re-open this thread if the problem still persists, or start a new thread. Thank you for choosing TI parts for your project :-)
