Magnachip Semiconductor Corporation (NYSE: MX) launches new generation Low-Voltage Metal Oxide Semiconductor Field Effect Transistors (LV MOSFETs). It features lower Rss(on) for battery Protection Circuit Modules (PCMs) in smartphones.
With high-end 5G and LTE smartphones demand increasing constantly, extended battery life and strengthened protection features are becoming important. 5G phones need long-lasting batteries with high endurance to process the large amount of data for fast download and upload. Magnachip’s new generation LV MOSFETs comes with advanced overvoltage and overcurrent protection features which extend battery life and reduce overheating issues. The company began mass production of this new 6.5th generation (6.5G) product last month.
The product is expected to be used in a new 2022 flagship model from one of the world’s largest smartphone manufacturers.
The Rss(on) of this new 6.5G product is 20% lower than the previous version with the same chip size to reduce current loss and improve heat dissipation. This lower Rss(on) controls a high power density above 25W to prevent a battery from overheating and protect the PCM while the battery is being fast-charged. Also, PCM functionality has been greatly enhanced by an upgraded Electrostatic Discharge (ESD) protection diode. This diode mitigates a maximum of 2kV, based on the human-body model, of ESD to strengthen circuit protection and prevent damage to other smartphone components. Along with this powerful battery protection, the size of chip was significantly reduced to better meet the requirements of new smartphone models.
“Despite the current global chip shortage, we are confident that we can maintain a strong supplier capability for our customers as an integrated device manufacturer for these new 6.5G products,” said YJ Kim, CEO of Magnachip. “We will continue to maintain a close rapport with our existing customers and expand our presence in the global market at the same time.”
