Magnachip Unveils Super-Short Channel MXT MOSFETs for Smartphone Battery Protection Circuit Modules

SEOUL, South Korea, March 2, 2023 – Magnachip Semiconductor Corporation (“Magnachip”) (NYSE: MX) announced today that the company has released two seventh-generation MXT Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs)1, built on its Super-Short Channel technology, for the battery protection circuit modules in smartphones.

Super-Short Channel is Magnachip’s latest design technology to shorten the channel length between the source and the drain to significantly reduce RDS(on)2 and conduction losses during on-state operation. Magnachip is applying this technology first to the newly-released 12V MOSFET (MDWC12D028ERH) and 24V MOSFET (MDWC24D031ERH).

Thanks to Super-Short Channel technology, the sizes of these new MOSFETs have been reduced by 20%, while the RDS(on) of MDWC12D028ERH and MDWC24D031ERH is lowered by 40% and 24%, respectively, compared to the previous versions. With these enhanced product features, power loss is reduced when a battery is charging or discharging and a low operating temperature can be maintained for fast battery charging.

Magnachip plans to release compact-sized Super-Short Channel MXT MOSFETs with great power efficiency for the small batteries of wearable devices, such as smart watches and earphones, in the second half of 2023.

“The new Super-Short Channel technology has taken the performance of MXT MOSFETs to the next level.” said YJ Kim, CEO of Magnachip. “Magnachip will continue our efforts to advance technological innovation and deliver premium power management solutions satisfying the diverse and changing requirements of mobile device manufacturers.”
