New Super-Short Channel MXT MOSFETs from Magnachip

Magnachip Semiconductor announced that the company has released two seventh-generation MXT Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs), 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) 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.
