Part Number: TPS2388

Dears,

We use sifos test Class_Time_Tpdc (Classification Time Duration) fail, measurement value is 4.9ms below 5.6ms.

Is any way to adjust this value?

Eric,

The classification time is controlled by TPS2388 itself and there's no way to change that. However, the default TPS2388 classification time should pass AT sifos. Can you send me the original sifos report and capture the waveform of port voltage? Thanks.

Best regards,

Penny

Eric,

Can you dump your register values and which command did you use to turn on the port? A port voltage or drain voltage would also be helpful. Thanks.

Best regards,

Penny
