Hi team,
TPA3255 uses 4xSE output. The two channels of the left channel work well, and the two channels of the right channel work well, but when the left and right channels work together, there will be problems. After working for a period of time, some channels will not output (oscilloscope test output). Check the overheat protection signal is not triggered, do not know what cause. What should be checked? Any suggestions?
The following two situations can cause this problem:
1\When one channel of left channel and one channel of right channel work together
2\When four channels work together
Best Regards,
Amy
