Timing Diagrams
Normal Power-Up Sequence for Outputs
The STDEL register sets the delay between powering up
of each regulator at initial power-up (see power up
sequencing in Figure 19). Once all the internal power
good registers PGOOD[1-6] are all 1, then the global PG
pin goes high without delay.
The PORDEL register sets the delay for the POR flag pin.
The POR delay time starts as soon as AVIN pin voltage
rises above the system UVLO upper threshold set by the
PORUP register. The POR output goes low without delay
if AVIN falls below the lower UVLO threshold set by the
PORDN register.
