SANTA CLARA, Calif.--(BUSINESS WIRE)--June 7, 2000

IXYS Corporation (NASDAQ:SYXI) has announced the introduction of the IXHQ100 hot swap controller with a built-in power noise filter for negative bus voltages that are common in telecommunication systems.

An industry first, an active filter with a hot swap controller incorporates all of the active circuitry to protect circuit boards during live insertion or removal while the system power is on. Two new features are: a) active filtering to reduce bus voltage noise to the printed circuit board and thus eliminate or reduce passive filter components; b) auto detection of the loss of either ground or input voltage. "The IXHQ100 improves on existing hot swap chips in the market due to its active filtration feature and the elimination of a staggered pin structure common to existing designs," adds Sam Ochi, IXYS' Director of IC Research and Development.

The IXHQ100 controls an on-board series regulator to allow a wide input voltage range. It permits load current rise adjustments, presettable maximum current limits and user adjustable, fault indication turn off times to reset microprocessors and other synchronous board level systems. The IXHQ100SI is encapsulated in the TSSOP16 package and its operating junction range is -50C to +85C. A TO-220 packaged type (IXHP100S1) and evaluation boards are also available.

Major applications for these controllers are in central office switching hardware, telecommunication systems, computer and network appliances, circuit boards from -48V distributed power supplies and electronic circuit breakers.

Pricing in 100 and 1000 piece quantities for the IXHQ100S1 is $3.30 and $2.90 respectively. Delivery for small quantities is 4-6 weeks and production quantities are 16 weeks ARO.

IXYS Corporation offers a broad line of Power Semiconductors, including Power MOSFETs, IGBTs, Ultra-fast Reverse Recovery Diodes, thyristors and rectifiers, Multi-chip Modules, DCB ceramic substrates and Power Interface Integrated Circuits.
