Page 7 Control and Status Control hierarchy: Some features, such as output voltage, can be controlled both through hardware and firmware. For example, the output voltage is controlled both by the signal pin (Vprog) and the PMBus command, (Vout_command) . Using output voltage as an example; the Vprog signal pin has ultimate control of the output voltage until the Vprog is either > 3VDC or a no connect. When the programming signal via Vprog is either a no connect or > 3VDC, it is ignored, the output voltage is set at its nominal 12VDC and the unit output voltage can be controlled via the PMBus command, (Vout_command). Analog controls: Details of analog controls are provided in this data sheet under Signal Definitions. Common ground: All signals and outputs are referenced to Output return. These include ‘Vstb return’ and ‘Signal return’. Control Signals Voltage programming (Vprog): An analog voltage on this signal can vary the output voltage ± 10% of nominal, from 10.8VDC to 13.2VDC. The equation of this signal is: VOUT = 10.8 (Vprog * 0.96) where Vprog = 0 to 2.5VDC Between 2.5 and 3V the output stays at 13.2VDC. If Vprog is > 3V, or left open, the programming signal is ignored and the unit output is set at the setpoint of 12V DC. Load share (Ishare): This is a single wire analog signal that is generated and acted upon automatically by power supplies connected in parallel. The Ishare pins should be tied together for power supplies if active current share among the power supplies is desired. No resistors or capacitors should get connected to this pin. Remote_ON/OFF: Controls presence of the 12V DC output voltage. This is an open collector, TTL level control signal that needs to be pulled HI externally through a resistor. A turn OFF command either through this signal (Remote ON/OFF) or firmware commanded would turn OFF the 12V output. Enable: This is a short signal pin that controls the presence of the 12Vdc main output. This pin should be connected to ‘output return’ on the system side of the output connector. The purpose of this pin is to ensure that the output turns ON after engagement of the power blades and turns OFF prior to disengagement of the power blades. Write protect (WP): This signal protects the contents of the EEPROM from accidental over writing. When left open the EEPROM is write protected. A LO (TTL compatible) permits writing to the EEPROM. This signal is pulled HI internally by the power supply. Fan speed control: The speed of the fan can be increased above that point that is required for internal cooling. The speed of the fan cannot be decreased below internal cooling requirements. Status signals Output current monitor (Imon): A voltage level proportional to the delivered output current is present on this pin. The signal level is 0.04V per amp ± 0.25V. Input_OK: A TTL compatible status signal representing whether the input voltage is within the anticipated range. This signal needs to be pulled HI externally through a resistor. DC_OK: A TTL compatible status signal representing whether the output voltage is present. This signal needs to be pulled HI externally through a resistor. Over_temp_warning: A TTL compatible status signal representing whether an over temperature exists. This signal needs to be pulled HI externally through a resistor. If an over temperature should occur, this signal would pull LO for approximately 10 seconds prior to shutting down the power supply. The unit would restart if internal temperatures recover within normal operational levels. At that time the signal reverts back to its open collector (HI) state. Fault: A TTL compatible status signal representing whether a Fault occurred. This signal needs to be pulled HI externally through a resistor. This signal activates for OTP, OVP, OCP, INPUT fault or No output. PS_Present: This pin is connected to ‘output return’ within the power supply. Its intent is to indicate to the system that a power supply is present. This signal may need to be pulled HI externally through a resistor. Interrupt (SMBAlert): A TTL compatible status signal, representing the SMBusAlert# feature of the PMBus compatible i2C protocol in the power supply. This signal needs to be pulled HI externally through a resistor. Serial Bus Communications The I²C interface facilitates the monitoring and control of various operating parameters within the unit and transmits these on demand over an industry standard I²C Serial bus. All signals are referenced to ‘Signal Return’. Device addressing: The microcontroller (MCU) and the EEPROM have the following addresses: Device Address Address Bit Assignments (Most to Least Significant) MCU 0xBx 1 0 1 1 A2 A1 A0 R/W Broadcast 0x00 0 0 0 0 0 0 0 0 EEPROM 0xAx 1 0 1 0 A2 A1 A0 R/W Address lines (A2, A1, A0): These signal pins allow up to eight (8) modules to be addressed on a single I²C bus. The pins are pulled HI internal to the power supply. For a logic LO these pins should be connected to ‘Output Return’ Serial Clock (SCL): The clock pulses on this line are generated by the host that initiates communications across the I²C Serial bus. This signal requires an external pull-up to 3.3V. Serial Data (SDA): This line is a bi-directional data line. This signal requires an external pull-up to 3.3V.
communication interface simpler and more efficient. Master/Slave: The ‘host controller’ is always the MASTER. required by the clock pulses generated by the MASTER. ready to receive further instructions from the host controller. The maximum clock stretch interval is 25ms. beyond the clock stretch interval of the power supply. Figure 1. Example waveforms showing clock held low for more than 35ms. compromised if packet error correction is not employed. that the correct command is executed. message by the device that supplied the last byte. one command.

Operation (01) : By default the Power supply is turned ON at power up as long as Power ON/OFF signal pin is active HI. The Operation command is used to turn the Power Supply ON or OFF via the PMBus. The data byte below follows the OPERATION command. FUNCTION DATA BYTE Unit ON 80 Unit OFF 00 To RESET the power supply cycle the power supply OFF, wait at least 2 seconds, and then turn back ON. All alarms and shutdowns are cleared during a restart. Clear_faults (03): This command clears all STATUS and FAULT registers and resets the SMBAlert# line. If a fault still persists after the issuance of the clear_faults command the specific registers indicating the fault are reset and the SMBAlert# line is activated again. WRITE_PROTECT register (10): Used to control writing to the PMBus device. The intent of this command is to provide protection against accidental changes. All supported command parameters may have their parameters read, regardless of the write_protect settings. The contents of this register can be stored to non-volatile memory using the Store_default_code command. The default setting of this register is disable_all_writes except write_protect 0x80h. FUNCTION DATA BYTE Enable all writes 00 Disable all writes except write_protect 80 Disable all writes except write_protect and OPERATION Vout_Command (21) : This command is used to change the output voltage of the power supply. Changing the output voltage should be performed simultaneously to all power supplies operating in parallel using the Global Address (Broadcast) feature. If only a single power supply is instructed to change its output, it may attempt to source all the required power which can cause either a power limit or shutdown condition. Software programming of output voltage permanently overrides the set point voltage configured by the Vprog signal pin. The program no longer looks at the ‘Vprog pin’ and will not respond to any hardware voltage settings. If power is removed from the µController it will reset itself into its default configuration looking at the Vprog signal for output voltage control. In many applications, the Vprog pin is used for setting initial conditions, if different that the factory setting. Software programming then takes over once I 2C communications are established. Vout_OV_warn_limit (42): OV_warning is extremely useful because it gives the system controller a heads up that the output voltage is drifting out of regulation and the power supply is close to shutting down. Pre-amative action may be taken before the power supply would shut down and potentially disable the system. OC and OT_fault_ response (47, 50): The default response for both OC and OT is auto_restart (hiccup). Each register, individually, can be reconfigured into a latched state. Latched and hiccup are the only supported states. Restart after a latch off: Either of four restart possibilities are available. The hardware pin Remote ON/OFF may be turned OFF and then ON. The unit may be commanded to restart via i2c through the Operation command by first turning OFF then turning ON . The third way to restart is to remove and reinsert the unit. The fourth way is to turn OFF and then turn ON ac power to the unit. The fifth way is by changing firmware from latch off to restart. Each of these commands must keep the power supply in the OFF state for at least 2 seconds, with the exception of changing to restart. A power system that is comprised of a number of power supplies could have difficulty restarting after a shutdown event because of the non-synchronized behavior of the individual power supplies. Implementing the latch-off mechanism permits a synchronized restart that guarantees the simultaneous restart of the entire system. A synchronous restart can be implemented by; 1. Issuing a GLOBAL OFF and then ON command to all power supplies, 2. Toggling Off and then ON the Remote ON/OFF signal 3. Removing and reapplying input commercial power to the entire system. The power supplies should be turned OFF for at least 20 – 30 seconds in order to discharge all internal bias supplies and reset the soft start circuitry of the individual power supplies. Auto_restart: Auto-restart is the default configuration for recovering from over-current and over-temperature shutdowns. An overvoltage shutdown is followed by three attempted restarts, each restart delayed 1 second, within a 1 minute window. If within the 1 minute window three attempted restarts failed, the unit will latch OFF. If less than 3 shutdowns occur within the 1 minute window then the count for latch OFF resets and the 1 minute window starts all over again.

Page 12 Vin_UV_warn_limit (58): This is another warning flag indicating that the input voltage is decreasing dangerously close to the low input voltage shutdown level. Status_word (79): returns two bytes of information. The upper byte bit functionality is tabulated in the Status_word section. The lower byte bit functionality is identical to Status_byte. Fan_speed (D7): This register can be used to ‘read’ the fan speed in adjustment percent (0 – 100%) or set the fan speed in adjustment percent (0 – 100%). The speed of the fan cannot be reduced below what the power supply requires for its operation. The register value is the percent number, it is not in linear format. Invalid commands or data: The power supply notifies the MASTER if a non-supported command has been sent or invalid data has been received. Notification is implemented by setting the appropriate STATUS and ALARM registers and setting the SMBAlert# flag. Control and Read accuracy: The estimates below are believed to be reasonable under most operating conditions. However, these are typical numbers and not hard bound values that cannot be exceeded. In most nominal operating conditions the returned values are significantly better than these estimates. Note that temperature measurements are accurate around the shutdown limits and they get increasingly less accurate as the temperature level decreases.

Another separate EEPROM IC will provide another 128 bytes of memory with write protect feature. Minimum information to be included in this separate EEPROM: model number, revision, date code, serial number etc. LEDs Two LEDs are located on the front faceplate. The AC_OK LED provides visual indication of the INPUT signal function. When the LED is ON GREEN the power supply input is within normal design limits. The second LED DC/FLT is a tri-state LED. When GREEN there are no faults and DC output is present. When AMBER a fault condition exists but the power supply still provides output power. When RED then a fault condition exists and the power supply does not provide output power.
