instruction should be executed to each power supply to verify
that the command properly executed.
Voltage programming (Vprog): An analog voltage on this
signal can vary the output voltage ± 10% from 10.8Vdc to
13.2Vdc.
Hardware voltage programming controls the output voltage
until a software margin command is executed. Software
voltage programming (margining) permanently overrides the
hardware margin setting and the power supply no longer
listens to any hardware margin settings until power to the
controller is interrupted, for example if input power or bias
power is recycled.
When bias power is recycled to the controller the controller
restarts into its default configuration, programmed to set the
output as instructed by the Vprog pin. Again, subsequent
software commanded settings permanently override the
margin setting. As an example, adding a resistor between
Vprog and Output_return is an effective way of changing the
factory set point of the rectifier to whatever voltage level is
desired by the user during initial start-up.
Load share (Ishare): This is a single wire analog signal that is
generated and acted upon automatically by power supplies
connected in parallel. Ishare pins should be connected to each
other 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 the presence of the main 12Vdc
output voltage. This is an open collector 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.
Interlock: 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.
Status signals
Output current monitor (Imon): A voltage level of 3V = 167A,
or 18mV/A, proportional to the delivered output current is
present on this pin.
AC 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. In its default configuration, 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 activates for internal power supply failures such as
over temperature or over voltage shutdown.
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.
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’.
Pull-up resistors: The clock, data, and SMBusAlert# lines do
not have any internal pull-up resistors inside the power
supply. 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 is in compliance 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 is in compliance to the I²C /SMBus
specifications.
SMBUSAlert#: This hardware signal pin is normally HI. When
asserted (logic LO) it signifies to the system controller that the
state of the power supply has changed or that
communication errors occurred.
Basic Operation
PMBus™ compliance: The power supply is fully compliant to
the Power Management Bus (PMBus™) rev1.2 requirements.
The power supply clears the STATUS and ALARM registers and
the SMBAlert# signal after a successful read back of the
information in these registers, with the exception of
communications error alarms (PEC error, data error,
command error). If the alarm state is still present the status
