Automotive USB-C power delivery - Rear seat
Efficient charging to rear seat ports using Infineon's EZ-PD™ automotive USB-C power delivery (PD) solutions
Our EZ-PD™ high-integrated automotive USB-C PD chipset solutions support USB power delivery 3.0 and dynamic load sharing, delivering up to 100 W per port based on device power needs. This allows USB devices to charge while simultaneously sharing multimedia content with the vehicle. Compliant with USB Type-C and PD specifications, our solutions are the perfect choice for superior and efficient USB backseat charging on the go.
Scalable, highly integrated chipsets for USB-C backseat charging
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 chipset solutions for automotive USB rear seat power delivery below.
Scalability:
The chipset solution supports single- and dual-port designs for output power of up to 100 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."
- Dynamic load sharing
- Moisture Detection
- Output power throttling
- Authenticated firmware update
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 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/Tier 1 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 the 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 manufacturer's production line.
