Logic Control
Remote ON/OFF (PSON#)
Rev. 11.9.09_44 DS2900 2 of 4
The PSON# signal is required to remotely turn on/off the power supply. PSON# is an active low signal that turns on the +12VDC power rail. When this signal is not pulled low by the system, or left open, the +12VDC output turns off. The 3.30Vsb output remains on. This signal is pulled to a stanby voltage by a pull-up resistor internal to the power supply. The power supply fan(s) shall operate at the lowest speed Signal Type PSON# = Low PSON# = Open Logic level low (power supply ON) Logic level high (power supply OFF) Source Current, Vpson = low Power up delay: Tpson on delay 5 msec Accepts an open collector/drain input from the system. Pulled-up to the 3.30Vsb located in the power supply ON OFF MIN MAX 0V 2.0 V 0.8 V 4.125 V 4 mA 400 msec
Table 1 PSON# Signal Characteristics Power Good (PWOK#)
PWOK# is a power good signal and will be pulled LOW by the power supply to indicate that both the outputs are above the regulation limits of the power supply. When an output voltage 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, PWOK will be de-asserted to a HIGH state. The start of the PWOK# delay time shall be inhibited as long as the +12VDC output is in current limit or the 3.30VSB output is below the regulation limit. Signal Type: PWOK = High PWOK = Low Logic level low voltage, Isink = 4 mA Logic level high voltage, Isource = 200 A Sink current, PWOK = low Source current, PWOK = high PWOK delay: Tpwok on PWOK rise and fall time Power down delay: Tpwok off 1 ms 100 ms Open collector/drain output from power supply. Pull-up to 3.30Vsb external to the power supply Power not good Power Good MIN 0V 2.0 V MAX 0.8 V 4.125 V 4 mA 2 mA 1000 ms 100 sec 1000 msec
Table 2 PWOK# Signal Characteristics Power Supply Present Indicator (PRESENT#)
The PRESENT# signal is primarily used to provide a mechanism by which the host system can sense the number of power supplies physically present (operational or not). This pin is connected to ground in the power supply.
AC Input Present Indicator (ACOK#)
The AC OK# signal is used to indicate presence of AC input to the power supply. This signal shall be connected to 3.3 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 indiciate a loss of AC input to the power supply. Signal Type PRESENT# = Low PRESENT# = High Pull-up to 3.30Vsb through a resitor in the host system Present Not Present
