IEC 63563-11:2025

Qi Specification version 2.0 - Part 11: MPP Communications Protocol

IEC 63563-11:2025 describes Magnetic power profile (MPP) which is a protocol extension that provides additional messages, new power states/modes, new power transfer contract elements, and aims to provide the following functionalities:
• Operating Frequency Negotiation
• Cloaking (Power Pause)
• Generic Information Exchange
• Simultaneous Data Stream Transactions
• Fast PTx to PRx communication
• Maximum Power and Power Control Profiles Determination
• Extended Power Negotiation
• Extended PTx/PRx Identification and Capabilities
• Extended Control Error Packets and Received Power Packets
• Power Transmitter Battery Level Reporting
• Ecosystem Scalability
MPP extension allows devices to operate under Restricted mode (no PTx communication) at 360kHz without performing any explicit negotiation with the Power Transmitter. This flexibility enables devices with limited resources (e.g., devices with no FSK support) to take advantage of the frequency change feature.

Spécification Qi version 2.0 - Partie 11 : Spécification du système MPP

IEC 63563-11:2025 fournit une extension de protocole qui fournit des messages supplémentaires, de nouveaux états/modes de puissance, de nouveaux éléments de contrat de transfert de puissance, et vise à fournir les fonctionnalités suivantes:
• Négociation de la fréquence de fonctionnement
• Occultation (pause de puissance)
• Échange d'informations génériques
• Transactions simultanées de flux de données
• Communication rapide de PTx à PRx
• Détermination de la puissance maximale et des profils de contrôle de la puissance
• Négociation de pouvoir élargie
• Identification et capacités PTx/PRx étendues
• Paquets d'erreurs de contrôle étendus et paquets de puissance reçus
• Rapport sur le niveau de la batterie de l'émetteur de puissance
• Évolutivité de l'écosystème
L'extension MPP permet aux appareils de fonctionner en mode restreint (pas de communication PTx) à 360 kHz sans effectuer de négociation explicite avec l'émetteur de puissance. Cette flexibilité permet aux appareils disposant de ressources limitées (par exemple, les appareils ne prenant pas en charge la MDF) de tirer parti du phénomène de changement de fréquence.

Overview

IEC 63563-11:2025 - Qi Specification version 2.0, Part 11: MPP Communications Protocol defines the Magnetic Power Profile (MPP) extension for Qi wireless power systems. The MPP extension adds messaging, power states/modes, and contract elements to enable more flexible and scalable magnetic wireless power transfer between Power Transmitters (PTx) and Power Receivers (PRx). It supports enhanced negotiation, data exchange, and control capabilities while preserving a low‑resource operating option (Restricted mode at 360 kHz) for devices without full FSK/FMCW support.

Key topics and technical requirements

The standard expands core Qi behavior with the following technical areas and requirements:

• Operating Frequency Negotiation - mechanisms for agreeing on frequency changes between PTx and PRx.
• Cloaking (Power Pause) - defined states and messages to temporarily pause power transfer for safe events or coexistence.
• Generic Information Exchange - generic packets for capability and status sharing.
• Simultaneous Data Stream Transactions - support for parallel data channels alongside power control.
• Fast PTx → PRx Communication - low‑latency signaling to accelerate control and responses.
• Maximum Power & Power Control Profiles Determination - profiles and messages to determine and enforce power limits and control behaviors.
• Extended Power Negotiation - richer negotiation elements and contracts for dynamic scenarios.
• Extended Identification & Capabilities - enhanced PTx/PRx IDs and reported capabilities for interoperability.
• Extended Control Error Packets & Received Power Packets - improved telemetry and control feedback.
• Power Transmitter Battery Level Reporting - PTx-side battery/state reporting to inform PRx behavior.
• Ecosystem Scalability - provisions to scale multi‑device, multi‑transmitter systems.

The specification organizes behavior into phases such as Negotiation, Power Transfer, Cloak, and Extended Data Streams (see table of contents for phase‑level requirements).

Applications and who uses it

This standard is intended for:

• Wireless power system designers (PTx/PRx hardware and firmware teams) implementing advanced negotiation and control features.
• Product teams building multi-device charging mats, wearables, IoT endpoints, and consumer electronics that need robust coexistence, frequency management, or low‑resource receiver options.
• Certification and test labs validating compliance and interoperability across the Qi ecosystem.
• Ecosystem integrators and OEMs aiming for scalable multi‑transmitter/receiver deployments and better power management.

Practical uses include enabling constrained devices to benefit from frequency changes via Restricted mode (360 kHz), improving multi‑device simultaneous charging, enabling fast control loops for responsive power delivery, and exposing transmitter state (battery/health) to receivers.

FOREWORD
 The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprisingall
national electrotechnical committees (IEC National Committees). The object of IEC is to promote internationalco-
operation on all questions concerning standardization in the electrical and electronic fields. To this end andin addition
to other activities, IEC publishes International Standards, Technical Specifications, TechnicalReports, Publicly
Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Theirpreparation is entrusted to
technical committees; any IEC National Committee interested in the subject dealt withmay participate in this
preparatory work. International, governmental and non-governmental organizationsliaising with the IEC also
participate in this preparation. IEC collaborates closely with the InternationalOrganization for Standardization
(ISO) in accordance with conditions determined by agreement between the twoorganizations.
 The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
 IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
 In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence betweenany IEC
Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
 IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
 All users should ensure that they have the latest edition of this publication.
 No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage orother
damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) andexpenses
arising out of the publication, use of, or reliance upon, this IEC Publication or any other IECPublications.
 Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
