SLVUAW9C September 2016 – February 2020 UCD90320
The UCD90320 Power Supply Sequencer and Monitor supports a wide range of commands that allow an external host to configure, control, and monitor voltage rails and fans. Communication between the sequencer and the host is via an I2C electrical interface using the PMBus™ command protocol.
The PMBus specification describes the command protocol in general terms. This document describes implementation details that are specific to the UCD90320 Power Supply Sequencer and Monitor. If a command is not described in this document and it is supported by a UCD90320 device (see Table 2), it functions exactly as described in the PMBus specification. In which case, refer to PMBus specification for more details.
See the device-specific data sheet for a complete description of the features.
