This user’s guide describes two options of power distribution network (PDN), PDN-3A and PDN-3F, using the TPS6594133A-Q1 PMIC to supply and control power to J784S4 or J721S2 processors with independent MCU and Main power rails. These PDNs enable board level isolation of the MCU safety island and main voltage resources as required for implementing two desirable features of the processor:
The following topics are described to clarify platform system operation:
This section details how the TPS6594133A-Q1 power resources and GPIO signals are connected to the processor, discrete power resources, and other peripheral components.
