Control and Status Signals
Output Signals
ACOK
Signal used to indicate the presence of AC input to the power supply. A logic level HIGH will indicate that the AC input to the power supply is within the operating
range while a logic level LOW will indicate that AC has been lost.
This is an open collector/drain output. This pin is pulled high by a 10 kohm resistor connected to 3.3 V inside the power supply. It is recommended that this pin be
onnected to a 100 pF decoupling capacitor and pulled down by a 100 kohm resistor.

Signal used to indicate that main output voltage is within regulation range. The PWR_GOOD signal will be driven HIGH when the output voltage is valid and will be
driven LOW when the output falls below the under-voltage threshold.
This signal also gives an advance warning when there is an impending power loss due to loss of AC input or system shutdown request. More details in the Timing
Section.

Output Signals
PS_PRESENT
Signal used to indicate to the system that a power supply is inserted in the power bay. This pin is shorted to the standby return in the power supply. Recommended
pull-up resistor to VSB is 5.1 kohms. A 100 pF decoupling capacitor is also recommended.
PS_INTERRUPT
Active low signal used by the power supply to indicate to the system that a change in power supply status has occurred. This event can be triggered by faults such
as OVP, OCP, OTP, and fan fault. This signal can be cleared by a CLEAR_FAULT command. Recommended pull-up resistor to VSB is 5.1 kohms. A 100 pF
decoupling capacitor is also recommended.
