Renesas P9415-R wireless power receiver

Renesas Electronics has introduced the P9415-R wireless power receiver with WattShare technology. The 15 W 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. It features up to 5 W of transmit power capability in transmitter/receiver (TRx) mode and can receive up to 15 W on Qi transmitters, enabling quick and convenient mobile device charging on the go.

Based on Renesas’s 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 unit enables these mobile devices to change the power flow direction and deliver up to 5 W of power to charge other devices. The same wireless power coil and P9415 circuitry can be used to both receive and transmit power wirelessly.

Other features include: MTP non-volatile memory for easy firmware and device function updates; GUI support offering flexibility for user customisation; UVLO as low as 2.7 V for increased charging area and fast connections; IOUT sensing accuracy for foreign object detection capabilities; bidirectional communications to support proprietary authentication with encryption; and X-Y alignment circuitry for receiver/transmitter device alignment.
