Power and Temperature Measurement IC Announced By IXYS

Posted on: Friday, 23 June 2006, 09:00 CDT

IXYS Corporation (Nasdaq:SYXI) introduced today a power and temperature measurement mixed signal integrated circuit (IC), the MX844, developed by its Micronix division. The MX844 measures current, voltage, and temperature, and is a fully integrated subsystem that outputs serial data with a resolution of 3 1/2 digits plus sign. The fully differential sense amplifier has been optimized to measure very small voltages near ground and includes an internal temperature sensor with 0.2 degree C resolution. The device may be used with a 4-wire standard synchronous serial I/O interface or scan mode controlled by serial EEPROM. Additionally there is an asynchronous serial "talk-only" data output.

The MX844 operates with supply voltages between 4.5V to 40V and is compatible with most microcontrollers over an operating temperature of -40 degrees C to +85 degrees C. It is a necessary building block for monitoring power consumption, efficiency, and reliability with the convenience of digital outputs for interface control and communication.

"Our MX844 is a premier power and temperature measurement IC that is ideal for power systems in automotive and industrial applications where the user is concerned with battery capacity measurements, monitoring power, and systems energy efficiency," remarked Bob DeCaro, General Manager and Vice President of Micronix. "When operated with a low impedance shunt in series with the negative terminal of a battery, the MX844 can be used to determine the remaining battery capacity."

The MX844 has a standard lead time of 14-16 weeks and is available in an environmentally friendly, lead-free, QFN-28 package.

Micronix, a leader in the design of high-performance analog and mixed-signal integrated circuits, has produced over 400 application specific integrated circuits (ASICs) and application specific standard products (ASSPs) for the display, communications, consumer, and medical markets. Micronix is a subsidiary company of IXYS Corporation, a leading supplier of higher power semiconductors and modules for the global power market.

Any statements contained in this press release that are not statements of historical fact, including the performance, efficiency, lead time 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 Form 10-K for the fiscal year ended March 31, 2006. The Company undertakes no obligation to publicly release the results of any revisions to these forward-looking statements.
