Automotive USB-C charging head unit
Efficient charging at the head unit with Infineon's EZ-PD™ automotive USB-C charging chip-set solutions.
The USB charging module for the head unit application is also referred to as the breakout box (BoB) module. The module supports USB-C power delivery (max of 100 W) along with USB data connectivity from a phone, to support Apple CarPlay or Android Auto, or a USB storage device to stream content. The BoB could also support a USB hub to connect more than one USB device to the head unit.
Scalable USB-C charger chipset solutions for head unit charging
Infineon's EZ-PD™ automotive charging solution supports the ever-changing specifications for USB-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 below.
Scalability: The chip-set solution supports single- and dual-port designs for output power up to 100 W with external MOSFETs.
High integration: USB-PD controllers EZ-PD™ CCG7D and CCG7S with embedded CPU, flash, LDO, LIN interface, and DC-DC buck-boost controller allow for compact designs.
Configurability: Infineon's integrated flash enables proprietary charging solutions over USB PD, with validated firmware updates.
- Dynamic load sharing
- I2C interface to USB hub
- Output power throttling
- Authenticated firmware update
- Fault occurrence recording
- Programmable power supply
- VBATT to GND short protection
Configurable single- and dual-port USB PD controllers
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 be connected to the body control module (BCM) via the LIN interface. To do so, Infineon uses a proprietary software interface protocol called 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 the 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.
EZ-PD™ CCG7S/D is the heart of the charger module, which integrates a 24 V LDO enabling the controller to be powered up from the automotive battery.
