  • TPA3221: Startup timing in the datasheet

    TI Thinks Resolved
    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…

  • RE: TPA3221: TPA3221 issue in rest low

    Hello Jay, 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. best regards, Luis
