D2U5T-H3-7000-54-HU4C Application Note
PMBus Communication Protocol
ACAN55 Application Note
PMBus™ COMMANDS
This application note is applicable for the following product:
D2U5T-H3-7000-54-HU4C: Three Phase, AC Input 7000W/3500W; Back to Front Airflow; 54.0VDC; 129.6/64.8ADC
Standard PMBus™ Commands
All data communicated over the PMBus™ interface does NOT use PEC (Packet Error Checking) as defined by the standard for PMBus™ Power Systems Management Protocol Part 1 – General Requirements Rev 1.1.
Linear data formatting is used for all passed parameters. Block reads (where the loose byte received denotes the remaining byte to be clocked out) are not supported on this product series. A minimum of 300µs delay
between transactions (between STOP and START bits) is recommended for robust communications.
Note: 400KHz and 100KHz I2C communications are supported for the PMBus™ interface.
Note: The PMBus™ slave controller can “clock stretch” on ACK

Device Addressing Details
The D2U5T-H3-7000-54-HU4C supports an address for the module that is variable by use of the address bits A0 and A1 & A2 (accessible via the DC and signal I/O output connector; see ACAN-5x Application Note for
Interface Connector Card for more detail) as follows:

#RetOpCodexE2
Interpreting Received Values:
As defined the PMBus data format for this rectifier is the “Linear” format. The host system receives data that represents the actual value of the measured parameter such as volts, amps degrees
Celsius or any other units as appropriate. The rectifier is responsible for necessary processing of the raw data to present these values (thus reducing the onus on the “host system” to perform
these calculations).
The linear data format consists of two bytes:
•
•
An 11 bit two’s complement mantissa*
A 5 bit , two’s complement exponent (that provides the “scaling factor”)
Only the first 11 bits (mantissa) are used for the “Y” variable while the remaining 5 bits provide the exponent or “N” value; the following formula is used to calculate the “real world” value:
•
X = Y*2N
Where:
•
X is the calculated “real world” value in the appropriate units (V, A, °C etc.)
•
Y is a two byte two’s complement integer
• N is a two byte two’s complement integer
* Note while the READ_VOUT (Command Code x8B) uses the formula above “Y” is derived from the full 16 bits of the 2 byte returned data, and the exponent “N” is provided by the data returned from VOUT_MODE (Command Code x20).
