Part Number: TPD6S300

HI Sir

We use FL7101 Fresco controller IC with TPD6S300

Sometimes we insert typeC cable ,the CC1 will keep low (fail)

Do you have any Idea about this issue ?

1. without TPD6S300 => Function OK

2. with C287/C288 68pF => Sometime can't detect

3. without C287/C88 => Can't work

Hi Kai,

Thank you for your question. The CC line target capacitance (according to the USB PD Specs) has to be between 200pF and 600pF. The TPD6s300 has a typical internal capacitance of 74pF. Could you try to increase the capacitance of C287/288 to around 220pF? Maybe this will do the trick :-)

I hope this helps, and If this answers your question, PLEASE select This resolved my issue
