PWOK# (POWER GOOD)
PWOK is a power good signal and will assert HIGH when the outputs are within the regulation limits. PWOK will be pulled LOW by the
power supply to indicate when either output falls below regulation limits or when AC power has been removed for a time sufficiently long so
that power supply operation is no longer guaranteed. The start of the PWOK# delay time shall be inhibited as long as the +12 Vdc output is
in current limit or the 5.0 Vsb output is below the regulation limit.
PWOK Signal Characteristics

PWOK = High
PWOK = Low
To tLogic level low voltage, Ising = 4 mA
Logic level high voltage, Isource = 200 µA
Sink current, PWOK = low
Source current, PWOK = high
PWOK delay: Tpwok_on
PWOK rise and fall time
Power down delay: Tpson_off
Open collector/drain output from power supply.

PSKILL
The +12 Vdc output only from the power supply shall be disabled if the PSKILL input is high and V Standby will continue to be provided,
outputs may be enabled if this signal is low. The power supply includes a pull up to disable all outputs if this signal is open. PSKILL whall not
be connected during a hot insertion before all of the other pins are connected.
AC INPUT PRESENT INDICATOR (ACOK/L)
The ACOK signal is used to indicate presence of AC input to the power supply. This signal shall be connected to Vsb through a resistor on
the host system side. A logic “Low” level on this signal shall indicate AC input to the power supply is present. A Logic “High” on this signal
shall indicate a loss of AC input to the power supply.
