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.
