The unrivaled, cutting-edge technology embodied throughout our electronics product lineup is widely recognized among electronics manufacturers around the world. Our four main electronics businesses are battery separators including lithium-ion battery separators being proactively expanded as a leading supplier; LSI products featuring outstanding analog/digital mixed-signal technology; sensing devices such as magnetic sensors, current sensors, and infrared sensors; and UVC LEDs for water and air disinfection and sterilization applications with great potential to change people’s lives around the world.
Battery separators are environmentally friendly, high-performance materials for energy. Hipore™ lithium-ion rechargeable battery (LIB) separator is a flat microporous sheet of polyolefin with pore sizes ranging from 0.05 µm to 0.5 µm, for LIBs used in smartphones, laptop PCs, and other consumer electronics. US subsidiary Polypore International, LP makes Celgard™ LIB separator, which is particularly suitable for automotive applications, and Daramic™ lead-acid battery separator. More than 1 billion vehicles around the world utilize lead-acid batteries.
Our advanced mixed-signal LSIs feature low power consumption, high speed, and high precision. Mixed-signal LSIs play an essential role in bridging the gap between the analog information of the natural world and the digital information of electronic systems. Applications range from mobile communications including smartphones to automobiles, industrial equipment, and infrastructural equipment. The electronic compass, an advanced product which combines magnetic sensors and LSIs in a single device, finds widespread use in smartphones and other portable devices.
Hall elements are high-performance magnetic sensors used for control of brushless motors in optical disc drives and air conditioner fans, for image-stabilization mechanisms in digital cameras and smartphones, as well as many other areas. Hall ICs, comprising a combination of Hall elements and signal processing circuits, are used for mobile phone open/close detection switches and automobile power windows. Utilizing the thin-film compound semiconductor technology gained through experience in magnetic sensors, we are developing infrared (IR) sensors with smaller size for an expanding range of applications.
