1 Introduction

The MWPR1x24 is a wireless power receiver controller with integrated Bluetooth®

Low Energy ver. 4.2 compliant transceiver. The wireless power receiver controller

measures the current and voltage of the power output of the wireless power system and

transmits the values via Bluetooth LE to wireless power transmitter controller which

controls the power transfer.

The key characteristics and features of the system are:

• Enables single or multi-coil power transmitter topology.

• Variable Z-gap range (vertical movement) from 4 mm to 35 mm – depends on coils

setup. This range is limited by the 65-W power transfer programable thresholds.

• Modularity in design of power transmitter unit to extend the number of transmitter

coils to form a larger active area, which requires:

• Minor reconfiguration of software.

• Extension of the multiplexer hardware (coil switches and control signal

multiplexer).

• No major impact on the system topology.

• Fast wireless power transfer start-up time below 2.5 s (applicable for up to seven

transmitter coils).

• No power from powered device is needed for the power receiver unit to start-up.

• Support of one Power Class 1 (PC1) device with up to 65 W of PRU

output.Premium version support also one Qi-certified Power Class 0 (PC0) device

with support for 5-W and 15-W receivers.

• Peak power transfer efficiency (input of power transmitter unit to output of power

receiver unit) of over 86 % at the best coil placement and 65 W of power receiver

unit output.

• Power receiver unit output-integrated protections for over-power and over-current

scenarios.

• Run-time system resonant frequency tracking ranging from 100 kHz to 145 kHz to

improve the power-transfer efficiency.

• The power receiver unit power output acts as a constant 19.5-V source, forming an

alternative to standard 65-W (or lower) AC power adapters, and thus simplifying its

integration into the target system. Output voltage is adjustable.

• Foreign Object Detection during and prior to the power transfer.

• Interface for Bluetooth Low Energy (Bluetooth LE) out-band communication

between the power receiver unit and power transmitter unit for secured data and

firmware update transfer towards the power transmitter unit.
