D1U4-W-1600-54-HBxC Application Note
PMBus™ Commands
This application note is applicable for the following members of the product D1U4-W-1600-54-HBxC product series:
D1U4-W-1600-54-HB3C – Universal AC Input (Front to Back Airflow) Variant
D1U4-W-1600-54-HB4C – Universal AC Input (Back to Front Airflow) Variant
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 400μs delay between transactions
(between START and STOP bits) is recommended for robust communications.
Note: 100/400KHz I2C communications is supported for the PMBus™ interface.

Device Addressing Methods (See D1U4-54-CONC ACAN-52 for Additional Details)
There are two I2C buses provided by the D1U4-W-1600-54-HBxC power modules. These provide redundancy of the communication path to the slave I2C device (embedded in the
power module) by providing dual “master” buses.
Internally within the D1U4-W-1600-54-HxxC power module is located a NXP PCA9541A/03 2-1 I2C-Bus Master Selector device that allows operation with dual buses.
The dual master devices (each with it’s own dedicated bus) shall arbitrate between themselves by the method defined in NXP I2C Specification UM10204 Section 3.1.8 for details. The
bus that “wins” the arbitration process shall control the bus for the remaining duration of the transaction.
Since dual I2C buses are provided there are no variable address selections possible. Each NXP PCA9541A/03 address is fixed as 0xB0.
Also shown is the address of the EEPROM device resident in the power module.

Data Format
The products use the “linear” data format
Formula: X = Y * 2^N
X = the calculated (decimal) value
Y = the two-byte value read from PMBus expressed as a “twos complement value”; expressed as a decimal equivalent
N = the specific sensor exponent (scaling coefficient)
