Part Number: TAS5828M

Tool/software:

TAS5828M is powered by 24.5V, in BTL mode, with a 4-ohm load. There was a situation where the power supply pins and output pins of the power amplifier were burned out. What was the cause of this?

Hi Hu,

I assume you're referring to PVDD being powered by 24.5V correct? If so, was only PVDD damaged?

Would you be able to provide more details of the situation where damage is occuring? Is it during normal operation or shutdown?

If you could also provide schematic/layout files that would be helpful.

Regards,

Sebastian

Hi Hu,

Can you provide any details on the situation where damage occured?

If you can replicate this, would you be able to probe the voltage at PVDD and the class D output?

Were any speaker protection features enabled?

Regards,

Sebastian
