The P9261-3C-CRBv2 option includes the automotive-competent wireless electric power controller P9261 with MP-A13 3-coils reference layout as the wireless electrical power transmitter (TX). It provides a substantial lively charging spot with substantial efficiency and excellent EMC/EMI functionality. The reference style and design gives compliance to the Wireless Electric power Consortium (WPC) Qi 1.3 conventional EPP (Prolonged Power Profile) for 15W charging. It also supports proprietary charging profiles and is capable of 50W electrical power delivery.

The new P9261-3C-CRBv2 structure contains a Renesas RH850 automotive MCU as a host controller. This enables the procedure to give purposeful safety options that comply with Automotive Safety Integrity Stage B (ASIL B).

The P9261-3C-CRBv2 EVK can be controlled and monitored genuine-time by a graphical user interface (GUI). This GUI provides numerical readouts of critical parameters, such as the chosen coil, transmitter position, enter voltage, buck output present, Tx ability, and bridge voltage. The GUI enables uncomplicated programming changes and can update firmware. The GUI also supports tuning purchaser-unique variables connected to components style and design, these types of as configurations for international item detection (FOD).

“The P9261-3C-CRBv2 reference design demonstrates why automotive prospects utilize Renesas’ straightforward-to-use layout atmosphere to swiftly build upcoming-generation alternatives,” claimed Niall Lyne, Vice President, Automotive Energy and Movie Business enterprise Division at Renesas. “It offers the finest wireless charging functionality readily available and supports the hottest basic safety attributes needed by shoppers.”
