Microchip Technology has introduced two new device families which simplify the implementation of USB Type-C™ Power Delivery (PD) functionality across a range of applications.

The new products remove the complexity and high cost involved in implementing USB Type-C, enabling OEMs to bring the convenience and fast-charging capability of USB Type-C PD to more devices.

USB705x Family: Concurrent Charging and SuperSpeed Data Transmission

The new USB705x family is a set of USB 3.1 SmartHub devices with integrated support for Power Delivery, to enable fast device charging while removing the cause of users’ confusion about USB Type-C ports. The USB705x parts include two unique features which simplify USB Type-C PD implementations: HostFlexing and PDBalancing. HostFlexing simplifies the experience of using a docking station, making all USB Type-C ports function as the ‘notebook’ port. This eliminates the need for the cryptic labels on USB devices which try to explain the functionality of each USB Type-C port.

PDBalancing provides a means for manufacturers to manage system power centrally, saving consumers money by enabling them to charge multiple USB PD devices with less power overall. To meet consumer demand for both faster mobile device charging and faster data streaming, the USB705x family combines native support for USB Type-C PD with the 5Gbits/s SuperSpeed data rate specified by the USB 3.1 protocol.

The USB705x family provides a range of USB configurations. It also supports automotive use cases, allowing the graphical user interface of a mobile phone handset to be displayed on a vehicle’s screen while simultaneously charging the device.

  • Certified compliant with USB 3.1 Gen 1 specifications
  • Integrated USB 2.0 hub controller to support legacy devices
  • Supported by MPLAB Connect Configurator tool
  • Supports USB-IF BC1.2 charging profiles:
    • DCP: Dedicated Charging Port for power brick with no data
    • CDP: Charging Downstream Port, supplying 1.5A with data
    • SDP: Standard Downstream Port, supplying 0.5A with data
    • Custom profiles
  • Docking stations 
  • PC monitors 
  • Automotive infotainment equipment


FTM Development Board

The EVB-USB7050 evaluation platform supports four downstream ports: two USB 3.1 Gen 1 PD ports with USB Type-C connectors, and two USB ports with Type-A connectors. The platform also supports battery charging on all four downstream ports, supplying a maximum of 10A at any one time, and FlexConnect, a role-reversal technology which enables any of the downstream ports to be the Host port.


UPD301A: Dedicated, Stand-Alone Controller for USB Type-C Charging

Microchip’s new UPD301A is a stand-alone USB Type-C Power Delivery controller which greatly simplifies the implementation of basic USB Type-C PD charging functionality. 

With smartphones increasingly requiring more than the power supplied under the Battery Charging (BC) 1.2 standard, designers of various types of electronic system need to easily implement basic high-power charging. The UPD301A provides a simple, stand-alone solution for implementing USB Type-C PD charging. It supports both single- and dual-port operation.

  • Supported by MPLAB Connect Configurator tool
  • Standard PD power profiles: 15W/27W/45W/60W 
  • USB Power Delivery 3.0 media access controller
  • Easily supports second port with additional UPD350 USB-C transceiver
  • Rear-seat charging in vehicles 
  • Portable devices 
  • Public charging stations
