MagnaChip announced that it has launched a new MOSFET for wireless headphones to prevent overcharging of batteries. The MOSFET is designed to control excessive current flowing into wireless headphones when charging batteries to protect wireless headphones from damage.
According to the company, the wireless headset market size may jump from 120 million units in 2019 to 230 million units in 2020, with subsequent annual growth rates of up to 90%.
The new MOSFET is designed to prevent damage to the circuit of the wireless headset charging box by blocking excessive voltage from flowing to the charger. It also supports up to 2kV of electrostatic protection to protect charging safety. In addition to implementing strategies to increase the market share of wireless headset MOSFETs, MagnaChip is also preparing to expand the application of MOSFETs to wearable products such as smart watches and VR (virtual reality) headsets.
