Automotive USB power delivery - Head unit
Efficient charging and seamless USB data connectivity to head units using Infineon's EZ-PD? automotive USB-C charging chip-set solutions

-
On this page
Overview
Infineon's USB head unit power delivery solution, or breakout box module, offers two or more USB Type-C ports, enabling efficient connectivity between mobile devices and the automotive infotainment system. This facilitates Apple CarPlay, Android Auto, or media/data transfer. The module also provides USB power delivery (PD) of up to 140 W per port and can handle 48 V input directly from the vehicle battery.
Benefits
- Dynamic load sharing
- Moisture Detection
- Output power throttling
- Authenticated firmware update

About
Infineon¡¯s EZ-PD? automotive USB-C charging solution supports the ever-changing specifications for USB type-C chargers. A scalable solution makes it possible to create core designs that are flexible and cost-effective while also cutting down on development expenses and time-to-market. Check out the characteristics of our chip-set solutions for automotive USB head unit power delivery below.
Scalability:?The chipset solution supports single- and dual-port designs for output power of up to 140 W with external MOSFETs.
High integration:?Infineon's EZ-PD? USB PD controllers, including the CCG7D and CCG7S, feature an embedded CPU, flash, LDO, LIN interface, and DC-DC buck-boost controller, enabling compact designs. The EZ-PD? CCG7SAF single PD port controller takes integration to the next level by incorporating 2 x MOSFETs, resulting in an even more compact design and reduced bill of materials (BOM) cost.
Configurability: Infineon?s integrated flash enables proprietary charging solutions over USB PD, with validated firmware updates.
EZ-PD? CCG7S and EZ-PD? CCG7D are, respectively, single- and dual-port USB PD controllers with integrated DC-DC buck-boost controllers. Based on an Arm? Cortex? processor with 128 KB flash and GPIOs, they can interface with the body control module (BCM) over the LIN interface. In order to do so, Infineon uses a proprietary software interface protocol called the host protocol interface (HPI).
EZ-PD? CCG7S/D can receive OEM/Tier1 authenticated firmware with an external USB-to-Type-C dongle or over the LIN interface. It then uses the root of trust public key (RoTPK), RSA-2048, and SHA-256 algorithms to validate the firmware before updating its internal flash with the new firmware. This feature enables EZ-PD? CCG7S/D to be up-to-date with changing USB standards and any other firmware update that might be required for better functionality, even after the vehicle is out of the manufacturers? production line.
USB 3.0 Hub: EZ-USB? HX3 Automotive is a family of USB 3.2 Gen 1 (5 Gbps) hub controllers compliant with the USB 3.1, Gen 1 specification. EZ-USB? HX3 supports SuperSpeed (SS) (5 Gbps), High-speed (HS), Full-speed (FS), and Low-speed (LS) on all the ports. It has integrated termination, pull-up, and pull-down resistors, and supports configuration options through pin-straps to reduce the overall BOM of the system.
USB 2.0 Hub: EZ-USB? HX2G3 is a USB2.0 hub controller that supports Hi-Speed (480 Mbps), Full-Speed (12 Mbps) and Low-Speed (1.5 Mbps) data rates. EZ-USB? HX2G3 includes programmable USB2.0 PHYs and one serial communication block (SCB) that supports I2C or SPI. It can run from firmware (FW) downloaded from internal ROM, an external I2C EEPROM/ SPI Flash, or an external I2C master in dock applications.
By using high-quality components, such as automotive power MOSFETs from Infineon, engineers and automakers keep MOSFET-related failures to an absolute minimum. Our commitment to our customers¡¯ success and overall road safety is proven by the fact that all automotive MOSFETs bearing our name uphold the highest possible quality standards, far beyond AEC-Q101.
The portfolio of Infineon¡¯s automotive qualified OptiMOS? power MOSFETs offers benchmark quality from 20 V to 300 V, robust packages, and RDS(on) down to 0.4 m?.
The MOSFETs convince through:
- Leading RDS(on) performance in trench technologies
- Highest current capabilities in standard packages
- Lowest switching and conduction power losses
- Robust package technology

In order to do so, Infineon uses a proprietary software interface protocol called the host protocol interface (HPI).
EZ-PD? CCG7S/D can receive OEM/Tier1 authenticated firmware with an external USB-to-Type-C dongle or over the LIN interface. It then uses the root of trust public key (RoTPK), RSA-2048, and SHA-256 algorithms to validate the firmware before updating its internal flash with the new firmware. This feature enables EZ-PD? CCG7S/D to be up-to-date with changing USB standards and any other firmware update that might be required for better functionality, even after the vehicle is out of the manufacturers? production line.
USB 3.0 Hub: EZ-USB? HX3 Automotive is a family of USB 3.2 Gen 1 (5 Gbps) hub controllers compliant with the USB 3.1, Gen 1 specification. EZ-USB? HX3 supports SuperSpeed (SS) (5 Gbps), High-speed (HS), Full-speed (FS), and Low-speed (LS) on all the ports. It has integrated termination, pull-up, and pull-down resistors, and supports configuration options through pin-straps to reduce the overall BOM of the system.
USB 2.0 Hub: EZ-USB? HX2G3 is a USB2.0 hub controller that supports Hi-Speed (480 Mbps), Full-Speed (12 Mbps) and Low-Speed (1.5 Mbps) data rates. EZ-USB? HX2G3 includes programmable USB2.0 PHYs and one serial communication block (SCB) that supports I2C or SPI. It can run from firmware (FW) downloaded from internal ROM, an external I2C EEPROM/ SPI Flash, or an external I2C master in dock applications.
By using high-quality components, such as automotive power MOSFETs from Infineon, engineers and automakers keep MOSFET-related failures to an absolute minimum. Our commitment to our customers¡¯ success and overall road safety is proven by the fact that all automotive MOSFETs bearing our name uphold the highest possible quality standards, far beyond AEC-Q101.
The portfolio of Infineon¡¯s automotive qualified OptiMOS? power MOSFETs offers benchmark quality from 20 V to 300 V, robust packages, and RDS(on) down to 0.4 m?.
The MOSFETs convince through:
- Leading RDS(on) performance in trench technologies
- Highest current capabilities in standard packages
