IXYS Announces New Family of micro-Power Hall-Effect Switches

IXYS Corporation (NASDAQ:SYXI) announced today that its
Micronix division has introduced a new family of low cost micro-power
Hall-effect switches. The new MX887P, MX887D, and MX887U are designed
as reed switch replacements for a wide variety of commercial,
industrial, and automotive applications. These micro-power Hall-effect
switches feature ultra low offset canceling amplifiers for sensitive,
accurate and stable switch points, immunity to mechanical stress, and
solid state reliability.
   The MX887 family has a wide input operating voltage range of 2.5
to 5.5 volts that is ideal for battery powered applications due to
special circuitry enabling single digit micro-amp operating currents.
The on-chip power management circuitry reduces the effective average
operating current to just 5 microA at 3 volts, making it among the
lowest power devices in the industry. The switch output is activated
with omnipolar magnetic fields with as little as +/- 60 gauss,
providing excellent sensitivity and enabling the use of low-cost
magnets. Three simple digital output interface options are available:
the MX887P configured with a CMOS push-pull output, the MX887D with an
nMOS open drain pull-down output, and the MX887U with a pMOS open
drain pull-up output. All MX887 switches are available in lead-free,
TSOT-23, 3-lead, RoHS compliant packages.
   These integrated circuits can be used to sense magnetic fields and
sense currents and thus can be used to develop low cost current
sensors in power management circuits. The low power consumption make
them ideal for cell phones, PDA's laptop computers security systems
and appliances for detection and activation, especially for moving
lids, doors or covers.
   "Micronix has spent the past several years researching and
developing circuitry associated with Hall devices," says Micronix's
General Manager and Vice President, Bob DeCaro. "We are in the process
of developing a comprehensive line of magnetic and current sensing
devices. The MX887 family is our first product as a result of this
effort and we expect to be introducing a line of more sophisticated
Hall-effect products in the near future."
   The price levels associated with the MX887 are compatible with the
cost-sensitive manufacturing requirements of high volume, handheld
consumer devices, with a standard lead time of 16 weeks or less.

   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
