4 SPAFCBK-14G The following section defines the input and output signals from the power supply. All digital signals should be compatible with +3.3 volt LVTTL logic levels. All control signal lines share the same return used for +3.3 volt standby (3.3 VSB). 5.1 POWER SUPPLY ENABLE (PS_ON) The PS_ON signal is required to remotely turn on/off the power supply. PS_ON is an active low, below 0.7 V signal that turns on the 12 VDC power rail. In the low state this input will not source more than 4 mA of current. The 12 VDC output will be disabled when this input is driven higher than 2.1 V, or open circuited. See PS_ON Signal Characteristics Table. Accepts an open collector/drain input from the system. Signal Type: Input signal to the power supply Pull-up to 3.3 VSB located in power supply. PS_ON = Low, PS_KILL = Low ON PS_ON = Low, PS_KILL = Low OFF PS_ON = Low, PS_KILL = Open OFF MIN MAX Logic level low (power supply ON) 0 V 0.7 V Logic level high (power supply OFF) 2.1 V 3 V Output Source current, VPS_ON_L= low 4 mA Table 1. PS_ON Signal Characteristics 5.2 POWER OK (PW_OK) PW_OK is a power ok signal and will be pulled HIGH by the power supply to indicate that all the outputs are within the regulation limits of the power supply. When 12 VDC main output is < 10.9 V or > 13.2 V, or if any of the outputs fail due to over current protection, over voltage protection, over temperature, or fan failure then this output will be driven LOW. In the event AC mains power is lost, this signal must be driven LOW at least 20mS before the +3.3 VSB output is lost. The output will be an open collector/drain. It will be capable of driving the output below 0.4V with a load of 4 mA. The start of the PW_OK delay time is inhibited as long as any power supply’s 12 VDC output is in current limit. See PW_OK Signal Characteristics Table below. Open collector/drain output from the power supply. Signal Type: Output signal from the power supply Pull-up to 3.3V located in power supply. PW_OK = High Power OK PW_OK = Low Power Not OK MIN MAX Logic level low voltage, Isink = 4ma 0 V 0.4 V Logic level high voltage, Isource = 200μA 2.4 V 3.3 V Input Sink current, PW_OK = Low 4 mA Output Source current, PW_OK = High 2 mA PW_OK delay: (T9) TPW_OK_ON 100 ms 1000 ms PW_OK rise and fall time (w/o decoupling cap) 100 μs Power down delay: (T10) TPW_OK_OFF_12V 1 ms 700 ms Table 2.

SPAFCBK-14G 5 5.3 INPUT VOLTAGE OK (AC_OK) This signal will be asserted, driven HIGH by the power supply to indicate that the input voltage meets the minimum requirements. After falling outside the input voltage requirements for more than 20 mSec, the signal must be driven Low. The output will be an open collector/drain. It will be capable of driving the output below 0.4 V with a load of 4 mA. See AC_OK Signal Characteristics Table below. Open collector/drain output from the power supply. Signal Type: Output signal from the power supply Pull-up to 3.3V located in power supply. AC_OK = High AC OK AC_OK = Low AC Low (Not OK) MIN MAX Logic level low voltage, Isink = 4ma 0 V 0.4 V Logic level high voltage, Isource = 200μA 2.4 V 3.3 V Input Sink current, AC_OK = Low 4 mA Output Source current, AC_OK = High 2 mA AC_OK delay: (T13) TAC_OK_ON 1500 ms AC_OK rise and fall time (w/o decoupling cap) 100 us AC_OK delay: (T8) TAC_OK_OFF 20 ms Table 3. AC_OK Signal Characteristics 5.4 PS_KILL This pin is used to force the 12 V main output off if the supply is removed from the system. At the system level this pin will be connected to the output return directly. When this input is low the power supply will operate. If the input is floating the 12 V main output will turn off while the 3.3 VSB will remain on. This signal overrides all other on-and-off signals. On the power supply connector, this pin is shorter than the others so it is a last-make and first-break contact. See PS_KILL Signal Characteristics Table below. Accepts a ground input from the system. Signal Type: Input signal to the power supply Pull-up to 3.3V located in the power supply. PS_KILL = Low, PS_ON = Low ON PS_KILL = Open, PS_ON = Low or Open OFF PS_KILL = Low, PS_ON = Open OFF MIN MAX Logic level low (power supply ON) 0 V 1.0 V Logic level high (power supply OFF) 2.0 V 3.3 V Source current, VPSKILL = low 4 mA Table 4.

6 SPAFCBK-14G 5.5 PRESENT The PRESENT signal is used to sense the number of power supplies in the system (operational or not).This signal is connected to the power supply’s output ground. See PRESENT Signal Characteristics Table below. Output from power supply that is connected to ground. Signal Type: Output signal from the power supply Pull-up to 3.3V located in system. PRESENT = Low Present PRESENT = High Not Present MIN MAX Logic level low voltage, Isink=4mA 0 V 0.4 V Logic level high voltage, Isink = 50μA 3.3 V Sink current, PRESENT = low 4 mA Sink current, PRESENT = high 50 uA Table 5. PRESENT Signal Characteristics 5.6 SMBAlert This signal indicates that the power supply is experiencing a problem that the user should investigate. This may be asserted due to Critical events or Warning events. See PSMI specification for further details. Open-drain output from power supply that is connected to ground. Signal Type: Output signal from the power supply Pull-up to 3.3VSB located in system. SMBAlert = Low Not Present SMBAlert = High Present MIN MAX Logic level low voltage, Isink = 4mA 0V 0.4V Logic level high voltage, Isink = 50μA - 3.3V Sink current, SMBAlert = low - 4mA Sink current, SMBAlert = high - 50μA Table 6. SMBAlert Signal Characteristics 5.7 POWER SUPPLY INTERFACE (PMBUS) The PMBUS interface uses a serial SMBus interface for communication between the power supply(s) and the system. PMBUS allows the system to access status and power sensors in the power supply. The power sensors monitor both input and output power. The status monitors various critical and non-critical conditions in the power supply. One pin is the Serial Clock (SCL). The second pin is used for Serial Data (SDA). Both pins are bi-directional and are used to form a serial bus. Output from power supply that is connected to ground. Signal Type: Output signal from the power supply Pull-up to 3.3VSB located in system. MIN MAX Logic level low voltage, Isink = 4mA 0V 0.4V Logic level high voltage, Isink = 50μA - 3.3V Sink current, SCL and SDA = low - 4mA Sink current, SCL and SDA = high - 50uA Table 7.

SPAFCBK-14G 7 5.8 POWER SUPPLY ADDRESSING This signal indicates that the power supply address locations will be determined by external settings through the PS_A0 and PS_A1 address signals. Accepts a ground input from the system. Signal Type: Output signal from the power supply Pull-up to 3.3V located in the power supply. MIN MAX Logic level low voltage, Isink = 4mA 0V 0.4V Logic level high voltage, Isink = 50μA - 3.3V Sink current, PS_A0 and PS_A1 = low - 4mA Sink current, PS_A0 and PS_A1 = high - 50uA Table 8.

Address Matrix 5.9 LOAD SHARING CONTROL The power supplies load share by using a single load share bus signal (ISHARE) connected between the power supplies for the 12V output. If the load sharing is disabled by shorting the load share bus to ground, the power system must continue to operate within regulation limits for loads less than or equal to the maximum specified. The failure of a power supply should not affect the load sharing or output voltages of the other supplies still operating. 5.10 LOAD SHARE SIGNAL CHARACTERISTICS The load share signal provides both output current information and the load sharing function. The characteristics of the load share signal are defined below in the following table: ITEM DESCRIPTION MIN NOM MAX UNITS Voltage of load share bus at specified max output Vshare; Iout = max - 8 - V current. dVshare/dIout; Iout >1A Slope of load share bus voltage with changing load. - 8 / Ioutmax - V / A Amount of current the load share bus outputs from Ishare sink; Vshare = 8V - - 0.5 mA each power supply sink. Amount of current the load share bus outputs from 4.0 I share source; Vshare = 8V - - mA each power supply source.

SPAFCBK-14G 9 It is expected that the vendor supports most of the standard set of commands as per the PMBus specification. However, the following set of “standard” commands MUST be supported at the minimum, either through PMBus access or other methods to retrieve the information related to power efficiency. Refer to SPAFCBK-14G PMBus Communication manual for more details about the PMBus Commands sets. COMMAND CODE COMMAND NAME TRANSACTION TYPE COMMENT Turns on/off power supply. 0x01 OPERATION Write Command argument determines ON/OFF 0x88 READ_VIN Read Read input voltage 0x89 READ_IIN Read Read input current 0x8B READ_VOUT Read Read output voltage 0x8C READ_IOUT Read Read output current 0x96 READ_POUT Read Read Output Power 0x97 READ_PIN Read Read Input Power Table 12. PMBus Commands A 32K bit EEPROM device (example: AT24C32CY6-YH-T) is used in the power supply for user information storage. The EEPROM address is determined by PS_A0 & PS_A1 settings. (Address Matrix Table).Write protection is enabled in default to prevent unintended write to the EEPROM. In order to write to the EEPROM, first the write protection needs to be disabled by sending the appropriate command to the PSU (Refer to SPAFCBK-14G PMBus Communication Manual for more details). There will be 2 separate LED indicators, one green and one amber to indicate the power supply status. There will be a (slow) blinking green POWER LED (OK) to indicate that AC is applied to the PSU and the Standby Voltage is available. This same LED shall go steady to indicate that all the Power Outputs are available. This same LED or separate one will blink (slow) or be solid ON amber to indicate that the power supply has failed or reached a warning status and therefore a replacement of the unit is/maybe necessary. The LED are visible on the power supply’s exterior face. The LED location meets ESD Requirements. Power Supply Condition Green (OK) LED Status Amber (FAIL) LED Status No AC power to all power supplies OFF OFF Power Supply Failure (includes over voltage, over current, over OFF ON temperature and fan failure) Power Supply Warning events where the power supply continues OFF Blinking to operate (high temperature, high power and slow fan) AC Present/ 12VSB on (PSU OFF) Blinking OFF Power Supply ON and OK ON OFF Table 13.
