Wireless Charging with System Control MCU

Wireless charging for cell phones is quickly becoming a defacto standard for smartphones. Thanks to this rapid adoption, wireless charging is being embraced in many other applications, such as wearable electronics, household electronics and a myriad of sensor-based internet of things (IoT) applications.

Renesas’s portfolio delivers the industry’s best flexible SoC architecture, efficiency and hardware/algorithm implementation. The R9A02G011 is a USB power delivery controller that is based on the Universal Serial Bus Power Delivery (USB PD) Specification Revision 3.0 and USB Type-CTM Cable and Connecter Specification Revision 1.3. This ensures simple compatibility between various products.

The P9242-G is a highly integrated, magnetic induction, wireless power transmitter that supports up to 15W in compliance with the WPC-1.2.4 Specification which is the latest version of the Qi standard and the most widely adopted wireless charging system worldwide.
