Power and Temperature Measurement IC Announced by IXYS

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. Additional information about Micronix and IXYS
