EZ-PD USB-C PD enables in-car charging while accessing infotainment
The EZ-PD CCG7D is a dual-port USB-C power delivery (PD) device by Infineon which has an integrated boost controller for in-car charging applications. The USB-C PD complies with the latest USB Type-C and PD specifications (Ver. 3.1) and is AEC Q-100 qualified.
It is specifically designed for automotive applications that support Display Port (DP) in alternate mode. It was implemented in collaboration with Chinese manufacturer, Li Auto, for its new SUV model L9. It enables USB devices to charge while simultaneously sharing multimedia content with the vehicle. The device is suitable for automotive charging applications, such as head unit chargers, rear seat chargers and rear seat entertainment systems, said Infineon.
“As a leading provider of USB-C PD solutions for consumer and computing applications, Infineon offers seamless interoperability for the automotive market by enabling both USB-C PD charging and display port alternate mode capabilities with the EZ-PD CCG7D,” said Ganesh Subramaniam, senior vice president and general manager, wired connectivity solutions at Infineon.
The CCG7D-based alternate-mode solution implements two USB-C ports, with one port supporting DP-Sink and the second port supporting DP-Source. Its use means a two-way multimedia entertainment centre can be implemented in the car, allowing USB devices to be charged as well as streaming video from the cell phone or PC to the car display and/or sending video to VR goggles. The integration reduces the bill of materials and provides an optimised footprint for solutions with an output power of up to 100W per port. In addition to the CCG7D, a single-port variant, the EZ PD CCG7S, is available which is also qualified to AEC Q-100.
Form factor reference designs of EZ PD USB-C PD solutions CCG7D and CCG7S are now available.
