Renesas Electronics Corporation has introduced the first 60-W wireless power receiver, the P9418, to deliver faster wireless charging experiences for smartphones, laptops and notebook devices. Boasting the industry’s highest power density, the wireless power receiver IC features Renesas’ exclusive WattShare™ technology to deliver up to 60 W 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 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.
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.
Key features of this single-chip WPC medium power wireless device include WattShare (TRx ) mode with up to 10W Tx capability; an embedded 32-bit Arm® Cortex®-M0 processor; best-in-class IOUT current sensing accuracy for enhanced foreign object detection capabilities; MTP non-volatile memory for easy firmware and device function updates; and bi-directional communications to support proprietary authentication with encryption. The P9418 also supports the I2C 400 kHz standard interface and GPIOs, offers various proprietary charging modes, and is WPC 1.2.4 compliant.
Customers can also combine the P9418 wireless charging receiver with Renesas’ power management portfolio, including its USB Type-C™ power delivery and battery charging devices, to accelerate the development of their applications.
