VIF FieldDescription

PD_Power_As_Source

Set based on transmit source capabilities (0x32)

  • Calculate the source power in milliwatts (mW) from the largest source PDO.

EPR_Supported_As_Source

Set based on transmit source capabilities (0x32)

  • TX source num valid EPR PDOs [5:3]

YES if EPR source is supported and TX Source Num Valid EPR PDOs is non-zero.

Has_Invariant_PDOs

Default set to YES and can be modified based on system.

A port has invariant PDOs if the port always advertises the same PDOs except when limited by the cable.

Port_Managed_Guaranteed_Type

Set based on Tx source info (0x78)

  • Port Type Shared Assured [31]

A port is guaranteed or assured if the power provided by the port is fixed.

A port is managed or not assured if the port power can change dynamically.

Send_Pings

Default set to NO and must not be modified.

Not supported by TPS25751 or TPS26750.

Master_Port

Default set to YES and must not be modified.

USB_Suspend_Can_Be_Cleared

Default set to YES.

FR_Swap_Type_C_Current_Capability_As_Initial_Sink

Default set to 0: FR_Swap not supported.

Not supported by TPS25751 or TPS26750.

PD_OC_Protection

Default set to YES if a TI integrated PD + BQ option is selected in Q1 in GUI.

Otherwise set to NO.

PD_OCP_Method

Set to 2: Both if user selects integrated PD+BQ option for Q1 in GUI. The field is ignored otherwise.

  • For non-integrated PD+BQ system, users need to determine what kind of OC the system implements (is set to <select> for non PD+BQ option).

Num_Src_PDOs

Set based on transmit source capabilities (0x32)

  • Number of valid PDOs [2:0]
Note: This field only applies for SPR PDOs; EPR PDOs do not apply towards this field.

Default set to 10 if PD + BQ option is selected in Q1 in GUI.

Src_PD_OCP_OC_Threshold

Default set if PD + BQ option is selected in Q1 in GUI.

Src_PD_OCP_UV_Debounce

Default set to 10 if PD + BQ option is selected in Q1 in GUI.

Src_PD_OCP_UV_Threshold_Type

Default set to 1: Percentage if PD + BQ option is selected in Q1 in GUI.

Src_PD_OCP_UV_Threshold

Default set to 70 if PD + BQ option is selected in Q1 in GUI.
