Renesas Electronics is pushing hard into wireless charging designs with the first 60W single chip wireless power transceiver using the company’s WattsShare technology.  

The 60W of the P9418 provides faster wireless charging experiences for smartphones, laptops and notebook devices. WattShare uses AC inductive coupling from charging from a basestation or from phone to phone.

“The P9418 is the latest first-to-market example of our fast wireless charging technology, and we are proud to continue leading the way to convenient and cost-effective wireless charging for a range of mobile devices with our robust, safe and field programmable wireless power solutions,” said Dr. Amit Bavisi, Vice President of Wireless Power Group, Mobility Infrastructure and IoT Power Business Division at Renesas. “With our broad portfolio of scalable wireless power solutions, we are excited to be part of transforming the charging experience for a wide variety of battery-powered applications.”

The chip can be configured in a 10W transmit mode from a phone to another device or as a 60W receiver of an AC power signal through magnetic induction. The P9418 builds on the proven P9415 wireless power receiver and provides an easy upgrade path for existing customers. The new P9418 also delivers advanced telemetry and proprietary charging protocols required for high-power applications.

The chip sis based around an embedded 32bit Arm Cortex-M0 microcontroller core with MTP non-volatile memory for easy firmware and device function updates and 400kHz standard I2C interface and GPIOs.

The high accuracy of the current sensing provides enhanced foreign object detection capabilities and bi-directional communications to support proprietary authentication with encryption

Customers can also combine the P9418 wireless charging receiver with Renesas’ power management portfolio, including its USB Type-C power delivery and battery charging solutions, to accelerate the development of applications.

The P9418 60W wireless power receiver is available now.
