August 29, 2019 — Microchip Technology announced two solutions that simplify USB Type-C PD for a range of applications.
As a USB-IF-certified USB 3.1 SmartHub device with integrated support for Power Delivery (TID1212), the USB705x family enables device charging and introduces PD implementations called HostFlexing and PDBalancing. The UPD301A is a standalone USB Type-C PD controller that is designed to simplifies the implementation of basic USB Type-C PD charging functionality, making it suitable for applications from rear seat charging in vehicles to portable equipment to public charging stations.
HostFlexing works to simplify the user’s docking station experience by allowing all USB Type-C ports to function as the “notebook” port, eliminating the need for labels that try and explain overall functionality of each USB Type-C port. PDBalancing provides a methodology for manufacturers to manage overall system power through centralized control.
The USB705x family combines native support for USB Type-C PD with the 5 Gbps SuperSpeed data rates of USB 3.1. Intended for docks, PC monitors and automotive infotainment, the family – consisting of the USB7050, USB7051, USB7052 and USB7056 – provides a range of USB configurations to meet varying PD and USB Type-C design needs. For example, the USB7050 supports three PD-enabled upstream and downstream USB Type-C ports, while the USB7056 provides only one upstream port alongside five traditional Type-A downstream ports. The hubs also support driver assistance applications that are available on all mobile handsets, allowing the graphical user interface of a phone to be displayed on a vehicle’s screen while simultaneously charging the mobile device.
The UPD301A provides a standalone solution for implementing USB Type-C PD charging in a variety of applications. The device supports both single- and dual-port operation and uses a pin-configurable implementation that focuses on ease of use. The UPD301 complements Microchip’s family of USB hubs and enables solutions from charge-only to full data, video and power management.
