In the desktop wireless charging space, user demand is shifting from “can charge” to “charges more and charges faster.” A single desk may hold two phones, a pair of earbuds, and even other devices that need topping up—traditional single-charger or single-MPP solutions are no longer enough.

Bieland has launched a new dual MPP 25W one-chip, triple-output wireless charging solution. It supports simultaneous 25W magnetic fast charging for two phones on the left and right, and also integrates earbuds wireless charging and one wired fast-charging output. A single controller IC handles the entire desktop charging need.

1. Dual MPP 25W: Two Phones Fast Charging Simultaneously

The solution uses a fully synchronous digital demodulation one-chip, triple-output transmitter controller IC. A phone charging coil is placed on each side, with single-channel power up to 25W, supporting the MPP magnetic protocol. When two phones are placed on it at the same time, both can enjoy a MagSafe-level fast charging experience.

It is compatible with the latest WPC Qi2.2 standard and supports MPP + BPP/EPP protocols. Whether it is an iPhone or a future Qi2-enabled Android flagship, it enables drop-and-align, high-efficiency charging.

2. Earbuds + Wired: Full Coverage for Multiple Devices

In addition to the two phone positions, the solution also integrates:

• Wired fast-charging output on the lower left: marked PDO, supporting the PD fast-charging protocol, and capable of charging an additional phone, earbuds charging case, or other devices via cable.
• Earbuds coil on the lower right: 5W wireless charging, compatible with AirPods and mainstream TWS earbuds.

A single desktop charging pad can simultaneously serve up to three devices via wireless fast charging plus one device via wired fast charging, completely eliminating power strips and cable clutter.

4. This PCB Leaves No Detail to Chance

The PCB for this solution measures 83×93mm, with a compact and well-organized layout. Key points:

• Center: one D9812 controller IC
• Left and right: one D9022 full-bridge IC each, driving the dual 25W coils
• Lower center: an LCD screen measuring about 30×20mm

During charging, the screen displays the charging power of each coil in real time, clear at a glance.

The D9812 controller IC offers abundant memory and hardware resources to support customization for various LED, OLED, and TFT-LCD displays, giving products a more high-tech feel.

5. Explosive Value

Solutions on the market that achieve dual MPP 25W often require two controller ICs or multiple chips working together, resulting in high cost and complex debugging. Bieland uses a single D9812 to handle all control for three wireless charging channels plus one wired output, greatly reducing BOM cost and development difficulty.

Meanwhile, features such as hardware-level OCP protection, adjustable drive speed (for EMC optimization), and USB in-system upgrades make this solution suitable for rapid mass production and convenient for subsequent maintenance and feature iteration.

6. Applicable Product Form Factors

Based on this solution, the following can be developed:

• Dual-phone magnetic wireless charging dock
• Multifunctional desktop charging station (dual phones + earbuds + USB output)
• Business/office wireless charging pad
• Custom multi-device charging stand
