    P9415-R Evaluation Board assembled with Coil 3. Overview The P9415-R-EVK Wireless Power Evaluation Board serves to demonstrate the features and performance of the 9415-R 15W Wireless Power Receiver with WattShare™ mode. Renesas P9243-GB-EVK Evaluation Board or any other Qi certified Extended Power Profile (EPP) transmitter can be used as the power transmitter for P9415- R-EVK Evaluation Board testing.

  • Page 4: Setup

    Required Software on Computer Visit the P9415-R-EVK webpage and download latest version of the P9415-R Wireless Power Pro GUI, and USB drivers from the Renesas website. The Window GUI software provides an intuitive graphical user interface for reading and writing to P9415-R registers and program custom user configurations to internal MTP memory.

  • Page 5: Usage Guide

    1. Set up the P9243-GB Evaluation Board (or other transmitter board) according to the board’s user manual and apply power. 2. Place the P9415-R-EVK Board on the transmitter coil surface with the coil back facing upwards. P9415-R- EVK PCB boards act as a spacer between Tx surface and Rx coil.

    P9415-R-EVK Evaluation Kit 4.5.2. Wattshare Tx Mode Input Voltage The P9415-R can transfer up to 5W of power in TRx mode. It follows the WPC 1.2.4 BPP protocol to transfer the power to other Qi-certified receivers such as Mobile devices, wearables and hearables. The maximum power delivered in TRx mode is dependent on the input voltage on VOUT pin, coil characteristics such as AC resistance, and the friendly metal around the coil.

  • Page 19: Fod Parameters In Receiver Mode

    P9415-R-EVK Evaluation Kit In the Extended Power Profile, there are two methods of foreign object detection (FOD). One is by measuring the system quality factor before entering the power transfer phase, and the other is to measure the power loss difference between the received power and the transmitted power during the power transfer phase.
