Hi,
The customer said he understood DC protection of TPA3221.
He thinks that there is not problem if trouble in output bridge is within only one FET even if it is broken in short mode, because the other FETs become Hi-z by the DC protection.
He asks how about the protection of a case multiple FETs in output bridge are broken in short mode.
I think consumer devices like audio are designed without considering multiple failure, in general.
Best regards,
Akio Ito
