Hi,
TPA2011D1 might be damaged since the quiescent current was approximately 300mA when our customer evaluated it with the test board.
Is this part damaged by the short circuit although it has the overcurrent protection as below?
Could you please give us your advice if there is the other cause?
In addition, could you please tell us the detection method(cycle by cycle, etc) about the overcurrent protection?
Best regards,
Kato
Hi Don-san,
Thank you for your reply.
Is your opinion correct?
The quiescent current is mentioned on page 3 of TPA2011D1 data sheet as below.
It was approximately 300mA when our customer evaluated it without the speaker load in the case of VDD = 3.3V.
I believe that TPA2011D1 was damaged.
So, is TPA2011D1 damaged by the short circuit?
In addition, could you please tell us the detection method(cycle by cycle, etc) about the overcurrent protection?
Best regards,
Kato
