– R_{SS(on) Typ.}below 1mΩ — delivering ultra-low on-resistance for battery protection circuits (PCMs)

– 48% reduction in specific on-resistance (Rsp) and 185% improvement in current density compared to the previous generation

– Designed to meet next-generation smartphone requirements for ultra-fast charging and high-efficiency battery protection

SEOUL, South Korea, April 2026 — Magnachip Semiconductor Corporation (NYSE: MX, “Magnachip”) today announced the launch of two new 8th-generation Ultra Low-Ron 12V low-voltage (LV) MOSFETs designed for high-performance smartphone battery protection circuits (PCMs). These new products target next-generation smartphones, where ultra-fast charging and energy efficiency are increasingly critical, and represent an expansion of Magnachip’s product lineup, strengthening its competitiveness in the mobile battery protection FET market. One of them is in mass production and is currently being supplied to a major global smartphone manufacturer, having demonstrated proven performance and reliability.

As smartphones incorporate advanced AI functionalities and increasingly high-performance applications, computational loads are rising, driving the importance of power efficiency and charging performance. As a result, MOSFETs used in battery protection circuits (PCMs) are required to deliver low on-resistance, high current density, and efficient performance within limited board space. In addition, the growing adoption of innovative form factors such as foldable and rollable devices further constrains circuit design space, increasing the importance of enhancing performance within the same footprint while reducing component count.

The new products are designed as main switching devices in smartphone battery protection circuits (PCMs), performing critical functions such as overcharge and over-discharge protection, as well as charge and discharge current control. They offer two key advantages:

First, by significantly reducing on-resistance within the same package size, the products minimize heat generation. For example, the MDWC12D013PERH achieves more than a 50% improvement in on-resistance (R_ss(on)) compared to Magnachip’s 7th-generation device of the same size, resulting in a temperature reduction of up to 10°C under identical test conditions. This reduced heat contributes to extended battery life and improved charging stability in smartphones.

Second, enhanced current density and pin-to-pin compatibility enable replacement and integration within existing circuit designs, reducing PCB footprint and the number of FETs required, which helps reduce production costs. This allows manufacturers to utilize the saved space for larger battery capacity or slimmer device designs.
