TAS5760M Internal Status in SPK_FAULT Mode

Other Parts Discussed in Thread: TAS5760M

Hi,

We would like to know the internal status in SPK_FAULT mode.
Although if SPK_FAULT pin becomes low, the output stage becomes Hi-z, how does this device work in internal status?
Could you please tell us the functions that are disabled using the block diagram as below?
We guess that it is output stage only.
Is our understanding correct?

Best Regards,
Kato

Hi, Kato-san,

Sorry, we are a little bit busy right now. I have asked my colleague to get back with you later this week.

Hi Don-san,

We believe this issue as below.
Is our understanding correct?

If SPK_FAULT pin is low, the power stage of TAS5760M is placed into shutdown and this output becomes hi-z.

Kato-san,

As per our discussion and the table 1 on page 34 of the TAS5760M d/s, Only the speaker output is turned off (Hi-Z) during /SPK_FAULT low. All other circuits are working and will check for removal of the fault condition once /SPK_SD toggled low for latching faults. For non-latching faults the TAS5760M will continue to check for removal of fault condition and resume once fault condition is cleared.
