3 Description

The TPS25751 is a highly integrated stand-alone USB

Type-C and Power Delivery (PD) controller optimized

for applications supporting USB-C PD Power. The

TPS25751 integrates fully managed power paths

with robust protection for a complete USB-C PD

solution. The TPS25751 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 competitive USB PD solutions.
