Software development

Digital Power Software
FUSION_DIGITAL_POWER_DESIGNER Fusion Digital Power™  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.

Some of the tasks you can perform with the GUI include:

  • Turn on or off the power supply output, either through the hardware control line or the PMBus OPERATION command
  • Monitor real-time data. Items such as input voltage, output voltage, output current, temperature, and warnings/faults are continuously (...)
