Clare, a wholly owned subsidiary of IXYS Corporation, located 20 miles north of Boston, Massachusetts, USA, designs, manufactures, and markets a wide variety of semiconductor devices.

Clare’s wafer fabrication facility features a 600V BCDMOS process on a bonded-wafer, silicon-on-insulator, trench-isolated technology for IC development. Monolithic silicon with high voltage vertical DMOSFETS along with CMOS logic and bipolar transistors from Clare address many applications requiring a high voltage interface. In addition, Clare’s optically-isolated techniques for relays and signal processing offer high voltage isolation between the load side and the system controller.

Clare is a pioneer in the development of optically isolated Solid State Relays (SSRs), and has become a leading supplier to the Telecommunications, Security, Utility Metering, and Industrial Control industries. Clare SSR solutions are rapidly replacing older electromechanical devices in many applications, thus improving safety and lowering costs, while minimizing equipment size and enhancing overall system performance.

Clare manufactures a broad range of products for the Telecommunications industry that includes phone-line interface and monitoring devices, DC Termination devices for ADSL/VDSL and SHDSL/ISDN applications, and Central Office products. Clare’s newest entries into the Central Office market include two new Line Card Access Switch devices with the highest guaranteed transient immunity in the industry: 1500V/ms. These robust devices are just the start of an entire family of such devices that will make the designer’s task much easier while reducing costs, minimizing time-to-market, and greatly improving product reliability.

Clare’s high-voltage and power expertise supports a growing line of standard devices. Power SSRs, SCR-based AC power switches, Field Effect transistors (FET), and IGBT and MOSFET gate drivers, both optically isolated and standard, round out a broad offering in the power market. In addition, Clare offers design services to the industry for custom development of high-voltage semiconductor devices: Bring your high-voltage semiconductor component design opportunities to Clare.

Clare offers LED drivers for lighting and display applications, and drivers for the newest electronic paper devices, such as those from E Ink. The new MXHV9910, answers the growing need in the illumination industry for a cost-effective, off-line, high-brightness LED driver. Clare’s existing products and its new entries lead the way into these new and rapidly growing markets.

With the recent introduction of xDSL DC termination ICs, new power SSRs, innovative high-voltage analog switches, and electroluminescent display driver products, Clare has firmly established itself as a major supplier in the Telecommunication, Consumer, Security, Power, Lighting, Industrial, Medical, and Display markets.

With a steady eye to the future, Clare continues to develop industry-leading products that offer higher levels of integration and electrical performance for manufacturers in all these markets and others.
