TPS25762-Q1: CC2 Not moving of TPS25762-Q1

Part Number: TPS25762-Q1

Tool/software:

I created an original board with the same circuit as the TPS25762 Eva Board.

I am downloading the program to the TPS25762 from the EEPROM via I2C.

It seems that the download is working at the hardware level (as seen in the waveform).

The terminal state of the TPS25762 on the original board is the same as that of the Eva Board.After downloading the program to the TPS25762, CC1 works, but CC2 does not.

I would appreciate your advice.

TPS25762のEva Boardと同じ回路でオリジナルBoardを作りました。

TPS25762にプログラムをEEPROMからI2Cでダウンロードしています。ハードレベル(波形で)でダウンロードは出来ているように見えます。

オリジナルボードのTPS25762の端子状態はEva Boardと同じです。

TPS25762にプログラムのダウンロード後 CC1は動きますが CC2が動きません。アドバイスをお願いします。

  • Hi Masahiro-san,

    Thanks for the feedback and I need more input for this question:

    1. Do you see any output voltage? What's the load you are using? Is it under BC1.2 or PD?

    2. Can you provide the waveforms of CC lines and Vout? How you find CC2 is not working? Not both CC lines will be high depending on the protocol, so I would like to confirm this first.

    Staring with one Rd to check if the BC 1.2 works might be a good starting point.

    BR,
