Magnachip Semiconductor Corporation has launched two seventh-generation MXT MOSFETs, constructed on its Super-Short Channel technology, for smartphone battery protection circuit modules.
Super-Short Channel is the company's latest design technology to significantly trim the channel length between the source and the drain to reduce RDS(on) and conduction losses through on-state operation. It is applying this technology first to the 12V MOSFET (MDWC12D028ERH) and 24V MOSFET (MDWC24D031ERH).
Thanks to Super-Short Channel technology, the sizes of these new MOSFETs have been decreased by 20%, while the RDS(on) of MDWC12D028ERH and MDWC24D031ERH is lowered by 40% and 24%, respectively, compared to the earlier versions. These improved product features lower power loss when a battery is charging or discharging, and a low operating temperature can be maintained for fast battery charging.
The company plans to launch these compact-sized MOSFETs for the small batteries of wearable devices, including smartwatches 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."
