TAS2557EVM: PPC3 :Thermal Characterization Limit Fail

Dear TI Team

   Thermal Characterization  Limit  awlays Fail, The speaker could not be heated to the specified temperature.

PPC3 setting ,as follow

  • Hello, 

    While the thermal characterization is running, is the speaker heating at all? If so, how close is it getting to the max temperature? 

    Also, what frequency are you running the thermal characterization at? You can try adjusting this value as your speaker may heat up faster at a different frequency. 

    Best Regards,
