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.

The TPS2576x-Q1 and TPS2577x-Q1 devices belong to a family of USB Type-C PD controllers for use in single or multi-port charging or data USB system applications. The TPS2576x-Q1 and TPS2577x-Q1 family supports an integrated System Power Management (SPM) Engine that manages multi-port power allocation policies (in the case of the TPS25772-Q1 dual-port PD controller) and dynamically adjusts USB port power based on events such as these: Connect or disconnect of a Sink device and its Sink Capabilities, thermal events measured through an external thermistor or temperature sensor, and engine status detected through a change in input supply voltage.
