The P9261-3C-CRBv2 solution includes the automotive-qualified wireless power controller P9261 with MP-A13 3-coils reference design as the wireless power transmitter (TX). It offers a large active charging area with high efficiency and exceptional EMC/EMI performance. The reference design offers compliance to the Wireless Power Consortium (WPC) Qi 1.3 standard EPP (Extended Power Profile) for 15W charging. It also supports proprietary charging profiles and is capable of 50W power delivery.

The new P9261-3C-CRBv2 design includes a Renesas RH850 automotive MCU as a host controller. This enables the system to provide functional safety features that comply with Automotive Safety Integrity Level B (ASIL B).

The P9261-3C-CRBv2 EVK can be controlled and monitored real-time by a graphical user interface (GUI). This GUI provides numerical readouts of key parameters, such as the selected coil, transmitter status, input voltage, buck output current, Tx power, and bridge voltage. The GUI enables easy programming changes and can update firmware. The GUI also supports tuning customer-specific variables related to hardware design, such as settings for foreign object detection (FOD).

“The P9261-3C-CRBv2 reference design demonstrates why automotive customers utilize Renesas’ easy-to-use design environment to swiftly develop next-generation solutions,” said Niall Lyne, Vice President, Automotive Power and Video Business Division at Renesas. “It offers the best wireless charging performance available and supports the latest safety features required by customers.”
