Renesas has added a  power receiver to its wireless power portfolio.

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

Based on Renesas’ WattShare technology, the device 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.
