The UCD91320 device is a 32-rail PMBus controlled power sequencer.

Dedicated pins (MONx) monitor up to 32 voltage rails in either analog or digital modes. 32 rail enable (ENx) pins allow regulators to be sequenced. 16 margining (MARx) pins can be used to push regulators to high or low limits (margins) for testing, or actively trim outputs for enhanced accuracy. The output state of 16 logical GPO (LGPOx) pins can be controlled by the state of GPIs, rail status, and other LGPOs.

Nonvolatile event logging preserves fault events after power dropout. The Black Box Fault Log preserves the fault information and the status of all rails. This occurs for the first fault as well as the last fault before a power down event. The cascading feature offers convenient ways to manage up to 128 voltage rails.

The Sequencer Studio™ software is an intuitive PC-based graphic user interface (GUI) that can configure, store, and monitor all system operating parameters.

The UCD91xxx devices utilize multiple security safeguards to maintain integrity of the device firmware and configuration. Because of this, TI may not be able to read out the device configuration and firmware during failure analysis or in the case of a return. Please keep record of the firmware version running on your device, as well as the configuration parameters in the device. This ensures that the TI team is able to replicate any conditions for a return.
