2 VIF Overview

The USB Implementers Forum (USB-IF) defines the design target and test criteria used to evaluate a product. Products that pass the test criteria are considered USB-IF certified and have the right to license the USB-IF Logos. USB-IF compliance testing is highly recommended to make sure of product functionality, cross-device compatibility, and minimize risk against potential safety hazards.

Validating a system prior to testing for USB Power Delivery compliance is critical in preventing false failures due to underlying design limitations, reducing the number of iterations needed to achieve compliance, and avoiding delays in production schedules.

TI recommends to have the following completed prior to testing USB-PD compliance on end products:

  • Validated hardware: this includes full design review on the schematic and layout, completed testing and validation, and anything else needed prior to shipping final product.
  • The associated TPS25751 or TPS26750 JSON (Application Configuration) file that is loaded on the validated hardware.
  • A completed Vendor Info File (VIF) based on the JSON (Application Configuration) file.
  • The Test ID (TID) and Vendor ID (VID) provided by USB-IF.
