5.6.3Power Good (Output)
Each power supply provides a power good signal. A pin must be allocated for this signal. This signal indicates that all outputs have reached acceptable operating voltage. The power good signal levels and sourcing/sinking requirements are shown in Table
Table

† Measured relative to the power supply DC common output ground pins.
The power good signal is held low until all outputs have reached at least 90% of their respective operating voltages. The turn on delay for the power good signal is between 100 and 1500 milli- seconds.
The power good signal is low for a minimum of 1 millisecond before any of the output voltages fall below the regulation limits. Tests are conducted with a maximum load and minimum line voltage.
