We use the single SOC solution (TDA4APE6), and use the PMIC TPS6594133ARWERQ1.
According to the EVM configuration document Powering Jacinto 7 SoC For Isolated Power Groups With TPS6594133A-Q1 + Dual HCPS (Rev. A)
GPIO9 of TPS6594133 has both “DISABLE_WDOG” input function and "EN_VIO_3V3" output function.
We referred to the PDN design reference document "J784S4 EVM Single Leo Dual HCPS PDN-3AFGM v0.29.pdf"
Won't the “DISABLE_WDOG” input signal conflict with the "EN_VIO_3V3" output signal? When I pulled the "DISABLE_WDOG" signal up to VSYS_3V3 using the jumper, the enable signal of the Load switch would also be pulled high and output VDD_IO_3V3.
Thanks!
