PMBus Communications
The products provide a PMBus digital interface that enables
the user to configure many aspects of the device operation as
well as monitor the input and output parameters. The products
can be used with any standard two-wire I
device. In addition, the device is compatible with PMBus
version 1.1 and includes an SALERT line to help mitigate
bandwidth limitations related to continuous fault monitoring.
Monitoring via PMBus
A system controller can monitor a wide variety of different
parameters through the PMBus interface. The controller can
monitor for fault condition by monitoring the SALERT pin,
which will be asserted when any number of pre-configured
fault or warning conditions occur. The system controller can
also continuously monitor for any number of power conversion
parameters including but not limited to the following:
•
•
•
•
•
•
Evaluation software
A Configuration Monitoring and Management (CMM)
evaluation software, is available for the products.

The SA0 and SA1 pins can be configured with a resistor to
GND according to the following equation.
If any one of those voltage applied to ADC0 and ADC1 is out
of the range from the table above, PMBus address 127 is
assigned. If the calculated PMBus address is 0 or 12, PMBus
address 127 is assigned instead. PMBus address 11 is not to
be used. The user shall also be aware of further limitations of
the addresses as stated in the PMBus Specification.
