3 Description
The TPS25751A is a highly integrated stand-alone USB Type-C and Power Delivery (PD) controller optimized for applications supporting USB-C PD Power. The TPS25751A integrates fully managed power paths with robust protection for a complete USB-C PD application. The TPS25751A also integrates control for external battery charger ICs for added ease of use and reduced time to market. The intuitive web based GUI asks the user a few simple questions on the applications needs using clear block diagrams and simple multiple-choice questions. As a result, the GUI creates the configuration image for the user’s application, reducing much of the complexity associated with USB PD applications.
