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

Rhea-AI Summary

On March 2, 2023, Magnachip Semiconductor Corporation (NYSE: MX) launched two new seventh-generation MXT Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) designed for smartphone battery protection modules. Utilizing Super-Short Channel technology, these MOSFETs have a 20% size reduction and notable decreases in on-resistance (R_DS(on)) by 40% for the 12V version (MDWC12D028ERH) and 24% for the 24V version (MDWC24D031ERH). This innovation aims to reduce power loss and maintain low operating temperatures during charging. Further advancements for wearable devices are expected in late 2023.

Positive

• Launch of seventh-generation MXT MOSFETs for smartphones.
• 20% size reduction and significant R_DS(on) decreases, enhancing efficiency.
• Plans for compact MOSFETs for wearable devices by late 2023.

Negative

• None.

SEOUL, South Korea, March 2, 2023 /PRNewswire/ -- 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 R_DS(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 R_DS(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."
