Integrated USB Type-C Power Delivery Controller IC

July 29, 2015 // By Graham Prophet
Integrated controller and other new devices support USB connectors with flip capability and two-way power delivery; Texas Instruments has introduced an all-in-one USB Type-C and USB Power Delivery (PD) controller, which integrates a port power switch and port data multiplexer.

The TPS65982 USB PD controller is, says TI, the only integrated circuit (IC) available that provides the full power path, operating as a Single- or Dual-Role Port and enabling a variety of host and device power implementations.

For applications requiring higher data rates, the TPS65982 can be combined with the 5.4-Gbps HD3SS460, the first USB Type-C cross-point switch. This solution enables USB connectors on either end of the cable to be flipped up or down, delivers power up to 100W, and supports Alternate Modes to distribute video over DisplayPort from the host to the end device.

For USB Type-C systems requiring up to 15W of power, engineers can choose the TUSB320 family to provide USB Type-C configuration channel (CC) logic and port control. These devices make it possible for a system to detect the orientation of the plug, and determine the appropriate USB specification and mode settings for the end equipment.

Each of the new TI devices meets USB Type-C Specification 1.1 (Engineering Change Notice as of June 22, 2015) published by the USB Implementers Forum (USB-IF), of which TI is a long-standing participant.

Features of these USB Type-C devices include:

  1. Single USB PD controller delivers power and data in multiple modes: The TPS65982 integrated PD controller and power switch delivers both power and data in several Alternate Modes. The TPS65982 can operate as a Single- or Dual-Role Port (DRP) for power and can be configured to support data as a downstream-facing port (DFP); an upstream-facing port (UFP); or as both host and device, known as a DRP.
  2. SuperSpeed switch transfers video data at low power: The HD3SS460 USB Type-C cross-point switch can support data rates up to 5.4 Gbps while offering standby power of 40 µW – more than 50% lower than other offerings – to extend battery life.
  3. USB Type-C CC logic: The TUSB320 family supports USB 2.0, USB 3.1 and VCONN, giving designers the flexibility to use these devices in multiple USB-enabled designs. Its low shutdown power of 8 mW benefits a variety of battery-powered applications.
