8.1 Overview

The TPS25730 is a fully-integrated USB Power Delivery (USB-PD) management device providing cable plug and orientation detection for USB Type-C and PD receptacles. The TPS25730 communicates with the other USB Type-C and PD port partner at the opposite end of the cable. The device also enables integrates a high current port power switch for sinking.

The TPS25730 is divided into several main sections:

  • USB-PD controller
  • Cable plug and orientation detection circuitry
  • Port power switch
  • Power management circuitry
  • Digital core
The USB-PD controller provides the physical layer (PHY) functionality of the USB-PD protocol. The USB-PD data is output through either the CC1 pin or the CC2 pin, depending on the orientation of the reversible USB Type-C cable. For a high-level block diagram of the USB-PD physical layer, a description of its features, and more detailed circuitry, see USB-PD Physical Layer.

The cable plug and orientation detection analog circuitry automatically detects a USB Type-C cable plug insertion the cable orientation. For a high-level block diagram of cable plug and orientation detection, a description of its features, and more detailed circuitry, see Cable Plug and Orientation Detection.

For a high-level block diagram of the port power switch, a description of its features, and more detailed circuitry, see Power Paths.

The power management circuitry receives and provides power to the TPS25730 internal circuitry and LDO_3V3 output. See Power Management for more information.

The digital core provides the engine for receiving, processing, and sending all USB-PD packets as well as handling control of all other TPS25730 functionality. For a high-level block diagram of the digital core, a description of its features, and more detailed circuitry, see Digital Core.

The TPS25730 also integrates a thermal shutdown mechanism and runs off of accurate clocks provided by the integrated oscillator.
