Motorola's Powerful Comeback! Edge 40 Pioneers Full-Link GaN for Unrestricted Fast Charging-Innoscience

According to the Q1 2023 global smartphone vendor rankings for key markets released by market research firm Canalys, Lenovo's smartphone business achieved counter-trend growth in key regions like Europe and Latin America, as well as in Brazil, one of the world's top five markets. Notably, its market share in Europe entered the top five for the first time in nearly six years, with Q1 shipments increasing by 13% year-on-year. These results are primarily attributed to Motorola under Lenovo's umbrella.

Recently, Motorola launched a series of new models, receiving positive market feedback. Among them, the Edge 40, released on May 10th, has garnered significant attention. This smartphone is equipped with the new MediaTek Dimensity 8020 chip built on a 6nm process, offering not only excellent performance but also effectively reducing power consumption and heat generation. It features 8GB of LPDDR4X RAM, 256GB of UFS 3.1 storage, and a built-in 4400mAh battery, meeting user demands for ample memory, high storage capacity, and long battery life. Significant improvements have also been made in screen refresh rate and camera capabilities.

Unlike previous models, the Edge 40 not only comes standard with a 68W Gallium Nitride (GaN) fast charger but also innovatively incorporates GaN chips into the phone's internal battery motherboard.

Allen from Lenovo's Product Development Department stated:

"The recent launch of new Motorola models has received a very positive response in overseas markets. This Edge 40 further innovatively utilizes GaN chips to achieve full-link fast charging both inside and outside the phone. This significantly improves internal space utilization and reduces peak heat generation by approximately 85%, marking a major breakthrough in charging technology for Motorola phones!"

According to reports, the Motorola Edge 40 incorporates Innoscience's VGaN bidirectional-conduction GaN chips (40V/4.8mΩ) internally. These chips feature characteristics such as the absence of a body diode and low on-resistance. To date, this is the world's only GaN chip integrated into a smartphone motherboard and mass-produced for end-user devices. The principle involves using one VGaN chip to replace the traditional two back-to-back Si MOS (Metal-Oxide-Semiconductor) transistors inside a phone, enabling lower conduction loss for the phone's battery charging and discharging functions. This ensures more efficient and safer phone charging.

This product was recognized as an Outstanding Technological Innovation Product in the 17th "China Chip" Awards in 2022 and has been successfully mass-produced in multiple smartphone models from brands like OPPO, Realme, and OnePlus.

Regarding the standard charger, the Edge 40's 68W charger has a maximum output power of 68.2W, demonstrating good compatibility with both phones and laptops. The GaN power device used inside (custom product INN650DAL02A) also comes from Innoscience.

This chip utilizes a DFN 5*6 package, supports ultra-high switching frequencies, and possesses characteristics like low Qg (gate charge), low Co(tr) (output capacitance), and no Qrr (reverse recovery charge) loss. These enable the compact size and high efficiency of the Edge 40's standard 68W charger. According to tests by ChargerLAB, the Motorola 68W charger achieves a power density of 1.01W/cm³, fitting comfortably in the palm. It can be considered a quality offering among official phone accessories.

The launch of the Edge 40's full-link GaN fast charging represents a significant attempt and breakthrough in Motorola's phone development history. The innovative integration of GaN chips inside the phone enables lower conduction loss for battery charging and discharging. This not only improves charging efficiency and reduces battery wear but also significantly saves precious internal space. Coupled with the introduction of the standard 68W GaN charger, which enables efficient external charging and alleviates battery life anxiety, it collectively provides consumers with an excellent full-link fast charging experience.
