Hi Dongbao.

The device is shutdown from short circuit when output is at considerably high current (~1.5A). The device may even play audio at high distortion levels due to clipping without protecting itself.

You can also consider the proposed external diagnostic circuits from this appnote: https://www.ti.com/lit/an/sloa250b/sloa250b.pdf
