to be pulled HI externally through a resistor. Maximum
sink current ≤ 4mA and the max voltage is 12Vdc. Open
collector (HI) on this signal indicates that the output
voltage is present.
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.
Maximum sink current ≤ 4mA and the max voltage is
12Vdc. Open collector (HI) on this signal indicates that
temperatures are normal.
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. Maximum sink current ≤
4mA and the max voltage is 12Vdc. Open collector (HI)
on this signal indicates that no Fault is present.
This signal activates for OTP, OVP, OCP, AC 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 i
2C protocol in the power supply. This signal
needs to be pulled HI externally through a resistor.
Maximum sink current ≤ 4mA and the pull up resistor
should be tied to 3.3Vdc. Open collector (HI) on this
signal indicates that no Interrupt has been triggered.
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:

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 is pulled up
internally to 3.3V by a 10kΩ resistor. The end user
should add additional pull up resistance as necessary to
ensure that rise and fall time timing and the maximum
sink current is in compliance to the I²C specifications.
Serial Data (SDA): This line is a bi-directional data line. .
This signal is pulled up internally to 3.3V by a 10kΩ
resistor. The end user should add additional pull up
resistance as necessary to ensure that rise and fall time
timing and the maximum sink current is in compliance to
the I²C specifications.
EEPROM
The microcontroller has 96 bytes of EEPROM memory
available for the system host.
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.
See the communications protocol for further information.
Communications Protocol
The I²C protocol is described in detail by the I
2C and
PMBus Serial Communications Protocol for the CAR
Family of Power Supplies
application note.
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 provides visual indication of
three different states of the power supply. When the LED
is GREEN then there are no faults and the DC output is
present. When the LED is AMBER then a fault condition
exists but the power supply still provides output power.
When the LED is RED then a fault condition exists and
the power supply does not provide output power.
