Hi,
please play some large audio signal under some thermal cycle to see whether the fault pin be triggered or not.
Too small Isat might lead to OC easy to happen.
thanks

Part Number: TPA3131D2 Hi, based on the latest datasheet and TI website MPN: TPA3131D2RHBR was in MSL 1, however, we still received physical in MSL 2. Kindly help to advice. Thanks.
Part Number: TPA3131D2 Hi,
I am reading TPA3131D2 speaker Amplifier datasheet.
Is FAULTZ pin Open Drain Type?
I check the datasheet chapter 6.3. It define a Rpull-up=100K ohm.
And EVM board schematic, if I install JP3 jumper to enable fault auto recovery…
Part Number: TPA3131D2 Hi Experts ,
Can you please check and guide us with possible root causes for the solder test failure ? Seems like solder lead coverage was less.
As per the TI recommedation , what is the baking condition and acceptance level of…
Part Number: TPA3131D2 Hi TIer
My customer use TPA3131D2 in the project. Until now , They finish the PCB manufacture.
AM0 AM1 AM2 all connected to GND which set Fsw = 400kHz.
But customer find that 400kHz's HD5 will affect the system performance. …
Part Number: TPA3131D2 Hi Team
My customer is using TPA3131D2 to drive speaker.
they find there is a fault when power up the device as configuring gain as 32db( the following picture is the waveform of startup. the channel 1 is Fault signal).
If they…
Part Number: TPA3131D2 Hi Team,
As the title described, customer found that each time they change the status of SDZ pin(pull down or pull high), the GVDD voltage will drop from 6.9V to 5.1V.
The same performance could be reproduced in our EVM.
Is it normal…
Part Number: TPA3131D2 Hi,
we're having some issues on some of our amplifier boards, where 10 out of 50 boards fail with FAULT pin going low. It seems like it is the DC protection that kick in, as we're measuring about 6.5v on one of the outputs (OUTPL…
Part Number: TPA3131D2 Hi Team,
We would like to adjust power limit dynamically with the TPA3131D2. Can we do it by changing the voltage on the PLIMIT pin on the fly?
Thanks!

Part Number: TPA3131D2 Hi Team,
I have one question on the statement below.
"In a single-ended input application, the unused input should be ac grounded at the audio source instead of at the device input for best noise performance"
If ac grounding…
