Chips simplify USB power delivery hubs
As one of the industry’s first USB-IF-certified USB 3.1 SmartHub devices with integrated support for USB power delivery, the USB705x family enables fast device charging and introduces PD implementations called HostFlexing and PDBalancing. The UPD301A is a standalone USB Type-C PD controller that significantly simplifies the implementation of basic USB Type-C PD charging functionality, from rear seat charging in vehicles to portable equipment to public charging stations.
HostFlexing allows all USB Type-C ports to function as the “notebook” port, eliminating the need for cryptic 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 centralised control, ultimately saving money for consumers by being able to charge a number of PD enabled devices with less overall power.
The USB705x family combines native support for USB power delivery over Type-C connectors with the 5 Gbps SuperSpeed data rates of USB 3.1. The chip family including 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 new USB power delivery 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.
With smartphones increasingly requiring more than standard BC 1.2 power, designers of electronic systems need to be able to easily implement basic high-powered charging in systems. The UPD301A provides a simple, standalone solution for implementing USB power delivery over Type-C 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 support designs from charge-only to full data, video and power management, while the USB705x and UPD301 come with a complete solution including the MPLAB Connect Configurator hub configuration tool, evaluation boards with schematics and Gerber files to reduce development time.
