1 Introduction

This user’s guide describes a power distribution network (PDN), PDN-0C, using two TPS6594-Q1 devices to supply either the DRA829V or the TDA4VM processor with independent MCU and Main power rails. DRA829/TDA4VM Dual PMIC PDN-0C enables board level isolation of the MCU safety island and main voltage resources as required for implementing two desirable features of the processor:

  1. MCU processor acts as independent safety monitor (MCU Safety Island) over the Main processing resources to ensure safe system operations.
  2. MCU processor maintains minimum system operations (MCU Only) to significantly reduce processor power dissipation thereby extending battery life during stand-by use cases and reducing component temperature.
Note: PDN-0C is recommended for all new designs and designs needing the additional functional safety coverage provided by the independent safety monitors found in PDN-0C.

The following topics are described to clarify platform system operation:

  1. PDN power resource connections
  2. PDN digital control connections
  3. Primary and secondary PMIC static NVM contents
  4. PMIC sequencing settings to support different PDN power state transitions for an advanced processor system
PMIC and processor data manuals provide recommended operating conditions, electrical characteristics, recommended external components, package details, register maps, and overall component functionality. In the event of any inconsistency between any user's guide, application report, or other referenced material, the data sheet specification is the definitive source.
