PSON is an active low signal that turns on the +12 Vdc power rail. When this signal is not pulled low by the system, or left open, the +12 Vdc output turns off. The 3.30 Vsb 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 Accepts an open collector/drain input from the system. Pulled-up to the 3.30 Vsb located in the power supply PSON = Low ON = Open OFF PSON MIN MAX Logic level low (power supply ON) 0 V 0.8 V Logic level high (power supply OFF) 2.0 V 4.125 V Source Current, Vpson = low 4 mA Power up delay: T 5 msec 400 msec pson on delay Table 1 PSON Signal Characteristics
