6.4 Quick Info

As presented in Figure 6-5, users reach to the Quick Info page after clicking on the FINISH icon upon verifying the device communication, depicted in Figure 6-4. As shown in Figure 6-5, this page can also be accessed by clicking on the Quick Info icon on the left side of the GUI. The Quick Info page provides the following features.

  • PMBus addresses of all the devices, supported by this GUI
  • All the important PMBus commands to control the TPS25990 eFuse, such as OPERATION (01h), POWER_CYCLE (D9h), MFR_WRITE_PROTECT (F8h), STORE_USER_ALL (15h), RESTORE_USER_ALL (16h), RESTORE_FACTORY_DEFAULTS (12h), and CLEAR_FAULTS (03h)
  • Provision to import and export the user defined configuration file
  • Option to enable or disable the Packet Error Checking (PEC) and to select the preferred PMBus speed
  • Information about device state, PGOOD, SMBA (If the GPIO4 pin is configured as 'SMBA Output' in the GPIO_CONFIG_34 (E2h) register.), key device parameters & fault status, and STATUS_WORD (79h)
  • Option to update (Clicking on the Update Status icon) the complete GUI as per the latest state in all the registers supported by the device

Note:

A correct value of input current (A) and input power (W) can only be obtained by updating RIMON in the GUI (as pointed out by placing a RED circle in Figure 6-5) so that it matches the resistance placed at the IMON pin on the EVM.
