Magnachip Semiconductor Corporation announced the launch of its 8th‑generation Ultra Low‑Ron 12 V BatteryFETs, a new line of low‑voltage MOSFETs designed for high‑performance smartphone battery‑protection circuits. The devices promise lower on‑resistance and higher efficiency, targeting next‑generation smartphones that demand faster charging and improved energy management.
The new BatteryFETs achieve on‑resistance below 1 mΩ and deliver a 48 % reduction in specific on‑resistance compared with the previous generation, while current density improves by 185 %. These technical gains translate into reduced heat generation, higher power‑delivery capability, and tighter control of battery‑charging profiles—critical attributes for modern mobile devices that push the limits of battery chemistry and charging speed.
Magnachip’s entry into the battery‑protection market aligns with its announced shift to a pure‑play power semiconductor company, following the exit of its display business. The smartphone battery‑protection segment is a growing niche, and the company’s new MOSFETs position it to capture a share of this demand. Competitors such as Infineon, ON Semiconductor, and STMicroelectronics also offer power‑management solutions, but Magnachip’s 8th‑generation technology offers a distinct performance advantage in on‑resistance and current density.
One of the new BatteryFETs is already in mass production and is being supplied to a major global smartphone manufacturer, indicating early customer validation. Magnachip also plans to introduce 22 V Ultra Low‑Ron products within the year, further expanding its low‑voltage portfolio for mobile devices.
Financially, Magnachip reported a 95.7 % YoY decline in Q4 2025 revenue to $40.6 million and a gross profit margin of 9.3 % versus 20.9 % in Q1 2025. The company is scheduled to release its Q1 2026 results on April 28, with analysts expecting revenue of $46.00 million and an EPS of ($0.22). Magnachip will showcase its new power‑semiconductor solutions, including the BatteryFETs, at PCIM Europe 2026 in Nuremberg, Germany.
