Hi team
Customer conducted the test that whether TAS5731M can recover form the High PVDD voltage. they set the PVDD to 27.5V which not exceeds the maximum value in datasheet, but after 2mins, the device cannot generates the output PIN1 PIN46 and PIN39 has no output and PIN36 has a 5.5V voltage. test the output stage with the multimeter diode gear, there is no obvious fault issue.
We wait for 2 days and retest the device, there is still no output. but I'm not sure whether customer set the 93.8% duty cycle limit during test.
Does that means the device broken due to the high voltage?
