6.1 Configured States
In this PDN, the PMIC devices have the following four configured power states:
• Standby
• Active
• MCU Only
• Pwr SoC Error
• Retention
In Figure 6-1, the configured PDN power states are shown, along with the transition conditions to move between
the states. Additionally, the transitions to hardware states, such as SAFE RECOVERY and LP_STANDBY are
shown. The hardware states are part of the fixed device power Finite State Machine (FSM) and described in the
TPS6594-Q1 and LP8764-Q1 data sheets, see Section 8.
