6.6.2 Emergency Shutdown
Figure 6-8 shows the emergency shutdown sequence.
Figure 6-8 Emergency Shutdown SequenceWhen the VSYS voltage crosses below VSYS_UVLO_5V, all power good pins are deasserted, and after 444 ns (nominal) of delay, all VRs shut down. Upon shutdown, all internal discharge resistors are set to 100 Ω to ensure timely decay of all VR outputs. Other conditions that cause emergency shutdown are the die temperature rising above the critical temperature threshold (TCRIT), and deassertion of the power good of any rail (configurable).
