The USB Type-C® and Power Delivery (PD) specification has expanded the capability of USB ports including support for higher power delivery over USB connection. With the widespread adoption of USB Type-C and PD applications and portable devices that can charge over USB, it has become increasingly important for single or multi-port charger systems to intelligently manage power schemes for reliable and safe operation.

This application note describes how the TPS2576x-Q1 and TPS2577x-Q1 family of USB Type-C PD controllers enable power delivery over USB for robust and reliable system operation using the System Power Management (SPM) Engine.
