Fusion Digital Power™ Designer

Fusion Digital Power Designer is the Graphical User Interface (GUI) used to configure and monitor select Texas Instruments digital power controllers and sequencer/health monitors. The application uses the PMBus protocol to communicate with the device over serial bus by way of a TI USB adapter.

Texas Instruments provides two tools to configure, monitor, and program select PMBus capable devices. 

Fusion Digital Power Designer

  • Configure and debug devices
  • Prepare programming files

Manufacturing tool

  • Configure and optionally calibrate devices
