Renesas Electronics has introduced the P9415-R wireless power receiver with Renesas’ exclusive WattShare technology as the newest member of its wireless power solutions portfolio. The new 15W wireless power receiver enables smartphones, power banks, and portable industrial and medical equipment, to wirelessly charge other mobile devices and accessories that also have wireless charging capabilities.

The P9415-R features up to 5W of transmit power capability in transmitter/receiver (TRx) mode, as well as receive up to 15W on Qi transmitters, enabling quick and convenient mobile device charging on the go.

“2020 will be the year wireless charging moves into the mainstream, expanding from premium smartphones to include mid-range devices, and gaining broader adoption into consumer and industrial devices beyond the smartphone market,” said Andrew Cowell, Vice President, Mobility, Infrastructure & IoT Power Business Division at Renesas. “With the P9415-R, we are excited to bring our state-of-the-art WattShare technology to a wider audience, offering customers broader access to robust, scalable and flexible solutions that enable quick, convenient, and cost effective wireless charging for portable devices.”

Based on Renesas’ proprietary WattShare technology, the P9415-R combines receiver and transmitter capabilities, allowing smartphones, smartwatches, truly wireless ear buds and other devices to be wirelessly charged simply by placing them on top of a smartphone or other industrial and medical portable devices.

In WattShare TRx mode, the P9415-R enables these mobile devices to change the power flow direction and deliver up to 5W of power to charge other devices. Customers can use the same wireless power coil and same P9415 circuitry to both receive and transmit power wirelessly.
