Renesas unveils first 60W wireless power receiver IC
Renesas Electronics has introduced the first 60W wireless power receiver, the P9418, to deliver faster wireless charging experiences for smartphones, laptops and notebook devices in the highest power density solution. Featuring Renesas’ exclusive WattShare technology, the highly integrated P9418 wireless power receiver delivers up to 60W of power in a single chip.
This enables quick and convenient charging on the go beyond smartphones, including device charging for a variety of portable computing devices.
“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.”
Based on Renesas’ proprietary WattShare technology, the P9418 is a highly-integrated single-chip wireless power transmitter/receiver IC (TRx) that can be configured to transmit or receive 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.
