UPD360 – Small Form Factor USB Type-C/PD Controller

The UPD360 is a highly integrated small form factor USB Type-C/PD controller compliant with USB Type-C™ specification and USB Power Delivery specification v.2.0.

UPD360 provides cable detection and orientation, and implements baseband communication with a partner USB Type-C/PD Device. UPD360 can function as a Standalone Power Delivery Controller (in UFP/DFP modes) or as a Companion Power Delivery Controller to an external MCU/SoC, using the integrated I2C/SPI interface.

UPD360 also integrates two VCONN FETs with Rp/Rd switching, a port power controller that supports up to 5V/3A on VBUS, with over-current and over-voltage detection.

UPD360 also supports Alternate Modes, like DisplayPort, HDMI and Thunderbolt. In the companion mode a software stack executes in the external MCU/SoC to support DRP modes, power profiles and alternate mode functionality.

UPD360 targets a wide range of applications in Consumer (Notebooks, Monitors, Docking Stations) and Industrial (Point Of Sale Systems, Printers) market segments.

UPD360 Features

  • Highly integrated USB Type-C/PD Port Controller
  • Integrated:
    • VConn FETS (per USB Type-C spec)
    • Rp/Rd/Ra resistors (per USB Type-C spec) and switch muxes
    • No external oscillator required - minimize BOM
    • 5V/3A port power controller (FET integrated)
      • Current/voltage limit internal
      • Supports sustained 3A with current limit at -3.3A
    • Voltage comparator integrated for USB Type-C Rp/RdRa detection
  • 20V tolerance on VBus via low cost external FET
