Compiler/TAS5731M: The TAS5731 Burn out the woofer

Part Number: TAS5731M
Other Parts Discussed in Thread: TAS5731

Tool/software: TI C/C++ Compiler

Some of the products shipped burn out the woofer.

Could you tell me what's the reason  the woofer burn out?

Is it related to the register-setting of the TAS5731?

  • Hi Banghong,

    It is suggested to do some debug as i cannot help to analyze from your description. Some clues are for your reference:

    1. To check what is the failure rate of the issue;
    2. To check whether this issue can be reproduced stably;
    3. To check whether similiar issue can be reproduce on TI EVM board on the same condition;
      1. Once upon items above can be checked, then go further to:
    4. Burn out: to check whether any short occurs in the output pin;
    5. To use a current probe to monitor the current through the inductor, which can check whether it is too much power that causes this issue;
      1. To reduce the volume to see whether this issue is eliminated;
    6. To check BST waveform and  PWM wavform when this issue occurs.
