From Pairing to Connectivity: Maxic Wireless Charging Solutions Power Panasonic ALPHA G5 Smart Ring

On September 8, Panasonic launched its ultra-flagship ALPHA G5, the world’s first four-drum all-in-one washer-dryer with heat pump. To deliver a smarter and more convenient control experience, the ALPHA G5 features the α-Watch Smart Ring, which supports magnetic wireless charging for easy attachment and removal, enabling intuitive control of the entire four-drum system anytime, anywhere.

The smooth experience of the α-Watch Smart Ring is powered by Maxic’s wireless charging solutions, featuring the transmitter MT5805 and receiver MT5728. After pairing with the washer or dryer via wireless charging, the ring connects through its built-in Wi-Fi module, enabling flexible remote control of all four units. When placed back on the machine, it automatically recharges through magnetic wireless charging, ensuring convenient use and long-lasting performance for a smarter, more effortless laundry experience.

MT5805 is a single-chip wireless charging solution integrating a 32-bit M0 processor, 32kB MTP memory, and 4kB SRAM. Compliant with the WPC Qi 2.0 standard, it supports proprietary wireless charging protocols and customizable functions. The chip delivers up to 15W output power and operates over a wide 4–20V input range. It features built-in fast-charging and supports UFCS, PD3.0, QC, FCP, and SCP protocols. MT5805 enables single-chip wireless charger designs and supports ultra-low-power mode.

MT5805 offers various protections, including over-voltage protection (OVP), over-current protection (OCP), under-voltage protection (UVP), and over-temperature protection (OTP). It also integrates dynamic power limiting with adjustable power output. Packaged in FCQFN3×4-24L, MT5805 is suitable for wireless charging transmitters in smartphones, wearables, medical devices, home appliances, and industrial equipment.

MT5728 is a wireless charging receiver compliant with the WPC Qi 2.0 standard, supporting BPP and EPP with a maximum wireless charging power of 30W. It also features 10W reverse charging to power other receivers. It integrates an ARM M0 processor with 8kB SRAM and 16kB MTP memory, supports proprietary wireless charging protocols, and incorporates a synchronous rectifier and LDO.

MT5728 offers various protections, including OVP, OCP, OTP. It supports I²C and configurable GPIO interfaces and is packaged in WLCSP54, suitable for wireless charging applications in smartphones, power banks, tablets, and other electronic devices.
