SRPS EN IEC 63563-11:2025

Qi Specification version 2.0 - Part 11: MPP Communications Protocol

Scope

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.
