Power MOS Gate Drivers IC and Hot-Swap IC Power Management Patents Awarded to IXYS Corporation

Santa Clara, CA - IXYS Corporation (NASDAQ:SYXI), announces that two important patents for its power management Integrated Circuit (IC) program were issued. US Patent # 6,917,227, issued July 12, 2005, covers Power MOS driver IC technology that enables higher efficiency single and half bridge gate driver configurations, without the cross conduction losses found in other drivers in the market. US Patent # 6,922,320 issued July 26, 2005, covers IXYS Hot-Swap Protection IC, which incorporates a sensor-less ground fault detection method to sense load disconnect.

US Patent # 6,917,227 relates to the elimination of cross conduction in the output required for gate drive IC products, and is a key element for reduction of power losses and noise generated by MOSFET and IGBT drivers. IXYS has developed a broad range of low side and half-bridge drivers targeted at a wide range of applications, including plasma display, motion control and power supplies.

US Patent # 6,922,320 relates to a method of eliminating the need for separate ground fault detection pins, as well as implementation of active noise filtering and short-circuit/over-current detection. IXYS method enables true 'two wire' cable connection systems, such as those in coaxial cables limited to two connections of the inner conductor and outer shield. This Hot-Swap approach would be beneficial for various markets, including remotely powered CATV, telecommunications, cell-phone antenna amplifiers, and active speakers.

Any statements contained in this press release that are not statements of historical fact, including the performance, rating, benefits, reliability and suitability of products for various applications may be deemed to be forward-looking statements. There are a number of important factors that could cause the results of IXYS to differ materially from those indicated by these forward-looking statements, including, among others, risks detailed from time to time in the Company's SEC reports, including its Annual Report on Form 10-K for the year ended March 31, 2005. The Company undertakes no obligation to publicly release the results of any revisions to these forward-looking statements.
