Part Number: TPA3221 Hi Support team,
We found the startup timing diagram of the AVDD and FAULT signal are not correct. The statement mentioned that the FAULT way stays low until the AVDD reached the UVP, And at the reset is low, the AVDD should be disabled…
Too much AC coupling capacitance may lead to input cap charging failure in the device startup. If you have additional questions make a new thread do not post further in old closed threads.
Part Number: TPA3221 Hi Ti Team，
I have a soundbar project using TPA3221. EMC has exceeded the standard in many places.
1，Please help confirm whether the TPA3211 schematic diagram and output filter parameters are reasonable ？
2，Is it reasonable to output…

Part Number: TPA3221 Hi
May i ask a question,
Will there be any potential issue if my bootstrap cap is not big enough? datasheet recommend 33nF, however our circuit miss mount a 3.3nF bootstrap cap.
