SAN JOSE, California, January 24 /PRNewswire/ --

- MIC94064/65 Series Aimed At Battery-Powered Consumer and Industrial 
Apps Requiring Small Footprint and Enhanced Power Management

Micrel Inc., (Nasdaq: MCRL), an industry leader in analog, high bandwidth
communications and Ethernet IC solutions, today launched the MIC94064/5, a
series of high-side load switches that extend Micrel's industry-leading
MIC9406x family of high-side load switch products. The MIC9406x family now
covers a wide range of battery-powered consumer and industrial applications
that require a variety of turn-on characteristics, including portable
computers, cell phones, and personal media devices. The MIC94064/5 series is
currently available in volume quantities, with pricing starting at US$0.37,
for 1K quantities.

"A natural extension of our highly successful MIC94060/1/2/3, the new
MIC94064/5 devices offer our customers even more design flexibility than ever
before," noted John Lee, director of mixed-signal and RF products, Micrel.
"With the introduction of the MIC94064/5 series, our customers can now pick a
device from the MIC9406x family with a turn-on time that is optimized for
their specific applications."

The MIC94064/5 offer an output voltage turn-on time of 115 micron s,
complementing the less than 1 micron turn-on time for the MIC94060/1 and 800
micron s turn-on time for the MIC94062/3. The MIC9406x feature a typical
R(DSON) of 77mohm. The devices operate with inputs ranging from 1.7V to 5.5V.
Each solution can be driven by a low 1.5V logic level, which is accomplished
by incorporating a novel built-in level shift circuitry that allows low
voltage logic to control higher voltage supplies. Battery time is greatly
extended in portable applications due to the low operating current of 2
micron A and a shutdown current of less than 1 micron A. The MIC94064/5 have
a slew rate controlled turn-on time of 115 micron s (typical) that prevents
in-rush current. In addition, the MIC94065 provides an active load discharge
circuit that insures capacitive loads retain no charge when the main switch
is in an OFF state. The MIC94064/5 series are available housed in the thin
4-pin 1.2mm x 1.6mm MLF(R) and Teeny(TM) SC-70-6 packages.
