Overview - IEC 63563-10:2025 (Qi Specification version 2.0, Part 10: MPP System Specification)
IEC 63563-10:2025 defines the Magnetic Power Profile (MPP) - an extension to the Qi v1.3 Baseline Power Profile (BPP) - to enable interoperable wireless power devices. The standard provides system-level requirements and models that manufacturers can use to implement compliant PTx (power transmitter) and PRx (power receiver) products that interoperate within the Qi ecosystem.
Key topics and technical requirements
The standard covers functional, mechanical and electrical aspects necessary for MPP implementations. Major technical topics include:
- System architecture and models
- PTx and PRx functional block diagrams and system models for interoperability.
- Authentication protocol
- Framework for secure device identification and handshaking between transmitter and receiver.
- Coil design (mechanical & electrical)
- Detailed guidelines for PTx and PRx coil construction and electrical properties, plus measurement of mated coil systems.
- Power delivery and profiles
- Definitions and requirements for MPP power profiles that extend Qi BPP, including system recommendations and specification notes.
- Operating and signaling methods
- Object detection, operating frequency considerations, and the requirement for digital pings (128 kHz / 360 kHz) as part of device discovery and negotiation.
- Measurement & estimation
- K estimation (coupling coefficient) methods and specifications for assessing coil coupling and alignment.
- Power control and safety-related behavior
- Output impedance, load transients, and procedures for setting maximum receiver power (Set Pr_max).
- Compliance and testing implications
- Specifications that drive interoperability testing and certification processes.
Practical applications and who uses this standard
IEC 63563-10:2025 is intended for:
- Wireless power product manufacturers designing PTx and PRx hardware and firmware to meet Qi MPP interoperability.
- Hardware engineers focused on coil design, EMI/EMC considerations and system integration.
- Firmware and protocol developers implementing authentication, digital pinging and power control algorithms.
- Test labs and certification bodies creating test plans for MPP interoperability and conformance.
- OEMs and product managers evaluating wireless charging options for consumer devices (smartphones, wearables, IoT devices) and accessory ecosystems.
Practical uses include designing interoperable wireless charging pads, vehicle-integrated wireless chargers, and accessory chargers that must work reliably with Qi-certified devices under MPP.
