(Power
I/O
Output
The signal output is driven high when input source is available and within
acceptable limits. The output is driven low to indicate loss of input power.
There is a minimum of 1ms pre-warning time before the signal is driven low
prior to the PWR_OK signal going low. The power supply must ensure that
this interface signal provides accurate status when AC power is lost.
Output
The signal is asserted, driven high, by the power supply to indicate that all
outputs are valid. If any of the outputs fail then this output will be hi-Z or
driven low. The output is driven low to indicate that the Main output is
outside of lower limit of regulation (11.4Vdc).
Output
The signal output is driven low to indicate that the power supply has
detected a warning or fault and is intended to alert the system. This output
must be driven high when the power is operating correctly (within specified
limits).
The signal will revert to a high level when the warning/fault stimulus (that
caused the alert) is removed.
Output
The signal is used to detect the presence (installed) of a PSU by the host
system. The signal is connected to PSU logic SGND within the power module.
Input
This signal is pulled up internally to the internal housekeeping supply
(within the power supply). The power supply main 12Vdc output will be
enabled when this signal is pulled low to +VSB_Return.
In the low state the signal input shall not source more than 1mA of current.
The 12Vdc output will be disabled when the input is driven higher than 2.4V,
or open circuited. Cycling this signal shall clear latched fault conditions.
Input
This signal is used during hot swap to disable the main output during hot
swap extraction. The input is pulled up internally to the internal housekeeping
supply (within the power supply).
The signal is provided on a short (lagging pin) and should be connected to
+VSB_Return.

The current sharing signal is connected between sharing units (forming an ISHARE bus). It is an input and/or an
output (bi-directional analogue bus) as the voltage on the line controls the current share between sharing units. A
power supply will respond to a change in this voltage but a power supply can also change the voltage depending
on the load drawn from it. On a single unit the voltage on the pin (and the common ISHARE bus would read 8VDC
at 100% load (module capability). For two identical units sharing the same 100% load this would read 4VDC for
perfect current sharing (i.e. 50% module load capability per unit).

Design Features
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 ‘SGND’.
Pull-up resistors: The clock, data, and SMBAlert lines do not have any
internal pull-up resistors inside the rectifier. The customer is responsible for
ensuring that the transmission impedance of the communications lines
complies with I2C and SMBus standards.
Serial Clock (SCL): The clock pulses on this line are generated by the host
that initiates communications across the I²C Serial bus. This signal needs to
be pulled HI externally through a resistor as necessary to ensure that rise
and fall time timing and the maximum sink current complies to the I²C /
SMBus specifications.
Serial Data (SDA): This line is a bi-directional data line. This signal needs to
be pulled HI externally through a resistor as necessary to ensure that rise
and fall time timing and the maximum sink current complies to the I²C /
SMBus specifications.
Digital Feature Descriptions
PMBus® compliance: The rectifier is fully compliant to the Power
Management Bus (PMBus®) rev1.2 requirements. This Specification can be
obtained from www.pmbus.org.
‘Manufacturer Specific’ commands are used to support additional
instructions that are not in the PMBus® specification.
All communication over the PMBus® interface must support the Packet
Error Checking (PEC) scheme. The PMBus® master must generate the correct PEC byte for all transactions, and check the PEC byte returned by the
rectifier.
I²C Bus Lock-Up detection: The device will abort any transaction and drop off
the bus if it detects the bus being held low for more than 35ms.
Communications speed: Both 100kHz and 400kHz clock rates are supported.
The rectifiers default to the 100kHz clock rate.
Packet Error Checking (PEC): The rectifier will not respond to commands
without the trailing PEC. The integrity of communications is compromised if
packet error correction is not employed. There are many functional features,
including turning OFF the main output, that require validation to ensure that
the desired command is executed.
PEC is a CRC-8 error-checking byte, based on the polynomial C(x) = x8 + x2 + x +
1, in compliance with PMBus® requirements. The calculation is based in all
message bytes, including the originating write address and command bytes
preceding read instructions. The PEC is appended to the message by the device
that supplied the last byte.
SMBAlert: The μC driven SMBAlert signal informs the ‘master/host’ controller
that either a STATE or ALARM change has occurred. Normally this signal is HI.
The signal will change to its LO level if the rectifier has changed states and the
signal will be latched LO until the rectifier receives a ‘clear_faults’ instruction.
The signal will be triggered for any state change, including the following
conditions:
Non-volatile memory is used to store configuration settings. Not all settings
programmed into the device are automatically saved into this non-volatile
memory. Only those specifically identified as capable of being stored can be
saved. (see the Table of Commands for which command parameters can be
saved to non-volatile storage).
•
Non-supported commands: Non supported commands are flagged by
setting the appropriate STATUS bit and issuing a SMBAlert to the ‘host’
controller.
•
If a non-supported read is requested the rectifier will return 0x00h for data.
Data out-of-range: The rectifier validates data settings and sets the data
out-of-range bit and SMBAlert if the data is not within acceptable range.
Master/Slave: The ‘host controller’ is always the MASTER. Rectifiers are always
SLAVES. SLAVES cannot initiate communications or toggle the Clock. SLAVES
also must respond expeditiously at the command of the MASTER as required by
the clock pulses generated by the MASTER.
Clock stretching: The ‘slave’ μController inside the rectifier may initiate clock
stretching if it is busy and it desires to delay the initiation of any further
communications. During the clock stretch the ‘slave’ may keep the clock LO
until it is ready to receive further instructions from the host controller.
The maximum clock stretch interval is 25ms.
The host controller needs to recognize this clock stretching, and refrain from
issuing the next clock signal, until the clock line is released, or it needs to delay
the next clock pulse beyond the clock stretch interval of the rectifier. Note that
clock stretching can only be performed after completion of transmission of the
9th ACK bit, the exception being the START command.

Invalid command
SMBAlert is asserted during power up to notify the master that a new
rectifier has been added to the bus.
The rectifier will clear the SMBAlert signal (release the signal to its HI state)
upon the following events:
•
•
Receiving a CLEAR_FAULTS command
Bias power to the processor is recycled
The rectifier will re-assert the Alert line if the internal state of the rectifier has
changed, even if that information cannot be reported by the status registers
until a clear_faults is issued by the host. If the Alert asserts, the host should
respond by issuing a clear_faults to retire the alert line (this action also
provides the ability to change the status registers). This action triggers another
Alert assertion because the status registers changed states to report the latest
state of the rectifier. The host is now able to read the latest reported status
register information and issue a clear_faults to retire the Alert signal.
Technical Specifications
Re-initialization: The I2C code is programmed to re-initialize if no activity is
detected on the bus for 5 seconds. Reinitialization is designed to guarantee that
the I2C μController does not hang up the bus. Although this rate is longer than
the timing requirements specified in the SMBus specification, it had to be
extended in order to ensure that a re-initialization would not occur under
normal transmission rates. During the few μseconds required to accomplish
reinitialization the I2C μController may not recognize a command sent to it. (i.e.
a start condition).
Read back delay: The rectifier issues the SMBAlert notification as soon as the
first state change occurred. During an event a few different states can be transitioned to before the final event occurs. If a read back is implemented rapidly by
the host a successive SMBAlert could be triggered by the transitioning state of
the rectifier. In order to avoid successive SMBAlert s and read back and also to
avoid reading a transitioning state, it is prudent to wait more than 2 seconds
after the receipt of a SMBAlert before executing a read back. This delay will
ensure that only the final state of the rectifier is captured.
Successive read backs: Successive read backs to the rectifier should not be
attempted at intervals faster than every one second. This time interval is sufficient for the internal processors to update their data base so that successive
reads provide fresh data.
Global Broadcast: This is a powerful command because it instructs all rectifiers
to respond simultaneously. A read instruction should never be accessed globally. The rectifier should issue an ‘invalid command’ state if a ‘read’ is attempted
globally.
For example, changing the ‘system’ output voltage requires the global broadcast so that all paralleled rectifiers change their output simultaneously. This
command can also turn OFF the ‘main’ output or turn ON the ‘main’ output of
all rectifiers simultaneously. Unfortunately, this command does have a side
effect. Only a single rectifier needs to pull down the ninth acknowledge bit. To
be certain that each rectifier responded to the global instruction, a READ instruction should be executed to each rectifier to verify that the command
properly executed. The GLOBAL BROADCAST command should only be executed for write instructions to slave devices.

Standard features
PMBus® Command set:
Supported features that are not readable: The commands below are
supported at the described setting, but they cannot be read back through the
command set.
Status and Alarm registers: The registers are updated with the latest
operational state of the rectifier. For example, whether the output is ON or OFF
is continuously updated with the latest state of the rectifier. However, alarm
information is maintained until a clear_fault command is received from the
host. For example, the shutdown or OC_fault bits stay in their alarmed state
until the host clears the registers.
A clear_faults clears all registers. If a fault persists after the clear_faults is
commanded, the register bit annunciating the fault is reset again.

Command Descriptions
Operation (0x01): Turns the 12V output ON or OFF. The default state is ON
at power up. Only the following data bytes are supported:
FUNCTION
To RESET the rectifier using this command, command the rectifier OFF, wait
at least 2 seconds, and then command the rectifier back ON. All alarms and
shutdowns are cleared during a restart.
Clear_faults (0x03): Clears all STATUS and FAULT registers and resets the
Alert# line of the I2C side in control. The I2C side not in control cannot clear
registers in the power supply. This command is always executable.
If a fault persists after the issuance of the clear_faults command, the specific registers indicating the fault first clears
have their parameters read, regardless of the write_protect settings. The
contents of this register cannot be stored into non-volatile memory using
the Store_user_code may command. The but then get set again to indicate
that the unit is still in the fault state.
WRITE_PROTECT register (0x10): Used to control writing to the PMBus
device. The intent of this command is to provide protection against accidental changes. All supported commands default setting of this register is
enable_all_writes, write_protect 0x00h. The write_protect command must
always be accepted.

OPERATION
Restore_Default_All (0x12): Restores all operating register values and
responses to the factory default parameters set in the rectifier. The factory
default cannot be changed.
Restore_default_code (0x14): Restore only a specific register parameter
into the operating register section of the rectifier.
Store_user_code (0x17): Changes the user default setting of a single register. In this fashion some protection is offered to ensure that only those
registers that are desired to be changed are in fact changed.
Restore_user_code (0x18): Restores the user default setting of a single
register.
Vout_mode (0x20): This is a ‘read only’ register. The upper three bits specify the supported data format, in this case Linear mode. The lower five bits

Fan_config_1_2 (0x3A): This command requires that the fan speed be
commanded by duty cycle. Both fans must be commanded simultaneously.
The tachometer pulses per revolution is not used. Default is duty cycle
control.
Fan_command_1 (0x3B): This command instructs the rectifier to increase
the speed of both fans. The transmitted data byte represents the hex equivalent of duty cycle in percentage, i.e. 100% = 0 x 64h. The command can
only increase fan speed, it cannot instruct the rectifier to reduce the fan
speed below what the rectifier requires for internal control. An incorrect
value will result in a ‘data error’.
Sending 00h tells the rectifier to revert back to its internal control.
Vout_OV_fault_limit (0x40): Sets the value at which the main output voltage will shut down. The default OV_fault value is set at 14.0Vdc. This level
can be permanently changed and stored in non-volatile memory.
Vout_OV_fault_response (0x41): This is a ‘read only’ register. The only
allowable state is a latched.
Vout_OV_warn_limit (0x42): Sets the value at which a warning will be
issued that the output voltage is too high. The default OV_warn limit is set
at 13.5Vdc. Exceeding the warning value will set the Alert# signal. This level
can be permanently changed and stored in non-volatile memory.
Vout_UV_warn_limit (0x43): Sets the value at which a warning will be
issued that the output voltage is too low. The default UV_warning limit is
set at 10.8Vdc. Reduction below the warning value will set the Alert# signal.
This level can be permanently changed and stored in non-volatile memory.
Vout_UV_fault_limit (0x44): Sets the value at which the rectifier will shut
down if the output gets below this level. The default UV_fault limit is set at
10Vdc. This register is masked if the UV is caused by interruption of the
input voltage to the rectifier. This level can be permanently changed and
stored in non-volatile memory.
Vout_UV_fault_response (0x45): This is a ‘read only’ register. The only
allowable state is restart.
Iout_OC_fault_limit (0x46): Sets the value at which the rectifier will shut
down at High/Low Line. This level can be permanently changed and stored
in non-volatile memory.
Technical Specifications
Iout_OC_fault_response (0x47): This is a ‘read only’ register. The only
allowable state is restart.
Iout_OC_warn_limit (0x4A): Sets the value at which the rectifier issues a
warning that the output current is getting too close to the shutdown level
at high/low line. This level can be permanently changed and stored in nonvolatile memory.
OT_fault_limit (0x4F): Sets the value at which the rectifier responds to an
OT event, sensed by the hottest sensor. The response is defined by the
OT_fault_response register.
OT_fault_response (0x50): Sets the response if the output overtemperature exceeds the OT_Fault_limit value. The default OT_fault_response is
hiccup (0xC0). The only two allowable states are latched (0x80) or hiccup.
The default response state can be permanently changed and stored in nonvolatile memory.
OT_warn_limit (0x51): Sets the value at which the rectifier issues a warning
when the hottest temperature sensor exceeds the warn limit.
Vin_OV_fault_limit (0x55): Sets the value at which the rectifier shuts down
because the input voltage exceeds the allowable operational limit. The
default Vin_OV_fault_limit is set at 76Vdc. This level can be permanently
lowered and stored in non- volatile memory.
STATUS_VOUT (0X7A): Returns one byte of information of output voltage
related faults.
STATUS_IOUT (0X7B): Returns one byte of information of output current
related faults.
Vin_OV_fault_response (0x56): This is a ‘read only’ register. The only allowable state is restart.
Vin_OV_warn_limit (0x57): Sets the value at which a warning will be issued
that the input voltage is too high. The default OV_warn_limit is 74Vdc. This
level can be permanently changed and stored in non-volatile memory.
Vin_UV_warn_limit (0x58): This is another warning flag indicating that the
input voltage is decreasing dangerously close to the low input voltage shutdown level. The default UV_fault_limit is 40Vdc. This level can be permanently raised, but not lowered, and stored in non-volatile memory.
The OC Fault limit sets where current limit is set. The rectifier shuts down
below the LV fault limit setting.
STATUS_INPUT (0X7C): Returns one byte of information of input voltage
related faults.
Vin_UV_fault_limit (0x59): Sets the value at which the rectifier shuts down
because the input voltage falls below the allowable operational limit. The
default Vin_UV_fault_limit is set at 38Vdc. This level can be permanently
raised and stored in non-volatile memory.
Vin_UV_fault_response (0x5A): This is a ‘read only’ register. The only allowable state is restart.
STATUS_BYTE (0x78): Returns one byte of information with a summary of
the most critical device faults.

STATUS_fans_1_2 (0X81): Returns one byte of information of fan status.
Manufacturer-Specific PMBus® Commands
Many of the manufacturer-specific commands read back more than two
bytes. If more than two bytes of data are returned, the standard SMBus
Block read is utilized. In this process, the Master issues a Write command
followed by the data transfer from the rectifier. The first byte of the Block
Read data field sends back in hex format the number of data bytes, exclusive
of the PEC number, that follows. Analog data is always transmitted LSB followed by MSB. A No-ack following the PEC byte signifies that the transmission is complete and is being terminated by the ‘host’.
Read back Descriptions
Single parameter read back: Functions can be read back one at a time using
the read_word_protocol with PEC. A command is first sent out notifying the
slave what function is to be read back followed by the data transfer.
Read_firmware_rev [0xD5]: Reads back the firmware revision of all three µC
in the rectifier.
Analog data is always transmitted LSB followed by MSB. A NA following the
PEC byte signifies that the transmission is complete and is being terminated
by the ‘host’.

General performance descriptions
Default state: Rectifiers are programmed in the default state to automatically restart after a shutdown has occurred. The default state can be reconfigured by changing non-volatile memory (Store_user_code).
Restart after a latchoff: PMBus™ fault_response commands can be configured to direct the rectifier to remain latched off for over_voltage,
over_temperature and over_current.
Each of these commands must keep the rectifier in the OFF state for at
least 2 seconds, except for changing to restart.
A power system that is comprised of a number of rectifiers could have
difficulty restarting after a shutdown event because of the nonsynchronized behavior of the individual rectifiers. Implementing the latchoff mechanism permits a synchronized restart that guarantees the simultaneous restart of the entire system.
A synchronous restart can be implemented by;
To restart after a latch off either of five restart mechanisms are available.
1. Issuing a GLOBAL OFF and then ON command to all rectifiers,
1. The hardware pin ON/OFF may be cycled OFF and then ON.
2. Toggling Off and then ON the ON/OFF (ENABLE) signal

command by cycling the output OFF followed by ON.
3. Remove and reinsert the unit.
4. Turn OFF and then turn ON AC power to the unit.
5. Changing firmware from latch off to restart.
The rectifiers 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 rectifiers.
Auto_restart: Auto-restart is the default configuration for over-current and
over-temperature shutdowns. These features are configured by the
Wiring diagram for output
CURRENT SHARING NOTS
Main current sharing is achieved using active current share method details Current sharing can be achieved with or without the remote sense (V_SENSE) connected to
the common load. +VSB outputs can be tied together for redundancy but total combined output power must not exceed the related standby power. The +VSB output
has an internal ORING MOSFEET for additional redundancy/internal short protection. The current sharing pin B5 is connected between sharing units (from an ISHARE
bus). It is an input and/or an output (bi-directional analogue bus) as the voltage on the line controls the current share between sharing units. A power supply will respond to a change in this voltage but a power supply can also change the voltage depending on the load drawn from it. On a single unit, the voltage on the pin (and the
common IHSARE bus would read 8VDC at 100% load. For two units sharing the same load this would read 4VDC for perfect current sharing (i.e. 50% load per unit). The
load for both the main 12V and VSB rails at the initial startup shall not be allowed to exceed the capability of a single unit. The load can be increased after a delay of
3sec (minimum), to allow all sharing units to achieve steady regulation.
