Renesas Releases Next-Generation WPC Qi 1.3-Certified Reference Design for Automotive In-Cabin Wireless Charging

Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced
semiconductor solutions, today released a next-generation customer reference
design for automotive wireless charging stations. The new P9261-3C-CRBv2
provides industry-leading features that enable automotive manufacturers to
quickly and efficiently deliver premium performance and safety features for
in-cabin wireless charging.

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.”
