Corporate Profile
Micrel Inc., is a leading global manufacturer of IC solutions for the worldwide Analog,
Ethernet and High Bandwidth markets. The Company’s products include advanced
mixed-signal, analog and power semiconductors; high performance communication,
clock management, Ethernet switch and physical layer transceiver ICs. Company
customers include leading manufacturers of enterprise, consumer, industrial, mobile,
telecommunications, automotive, and computer products. Corporation headquarters and
state-of-the-art wafer fabrication facilities are located in San Jose, CA with regional sales
and support offices and advanced technology design centers situated throughout the
Americas, Europe and Asia. In addition, the Company maintains an extensive network
of distributors and reps worldwide. Web: http://www.micrel.com.
Founded in 1978, Micrel maintains a portfolio of world class wafer fabrication processes
that enable the Company to produce new products faster than the competition. The
Company uses, singularly or in combination, CMOS, Bipolar and DMOS technologies
in its analog products. With the acquisition of Synergy Semiconductor in 1998, Micrel
has high-speed bipolar capability in the form of ASSET™ (All Spacer Separated Element
Transistor) process. This proprietary, patented bipolar technology employs a narrow
deep-trench isolation technique allowing for electrical isolation between adjacent circuit
elements. This means the Company can place multiple analog and digital functions
on the same IC without the various functions causing interference typically found when
alternate techniques are utilized.
Ethernet ICs
Micrel is an established leader in wired Ethernet networking with more than 300 million
ports shipped. The Company’s Ethernet products are widely used in Digital Home devices
(IP-STB, IP-TV, etc.), routers, access points, VoIP, Automotive, Industrial and Power
over Ethernet (PoE) applications, to name a few. There are a wide range of field-proven,
multi-port products in a variety of packages, including Physical Layer Transceivers (PHYs),
Embedded Controllers, Unmanaged and Managed Switches and System-on-Chip (SoC)
ICs with an integrated processor. Micrel’s comprehensive portfolio of Ethernet products
operate over commercial, industrial and extended temperature ranges, and are available
in a variety of environmentally friendly, lead-free packaging options.
High-Bandwidth and Communication Semiconductor Solutions
Micrel’s High-Bandwidth and Communication products include PMD (Physical Media
Device) ICs such as multi-rate (up to 4.25Gbps) Laser drivers, post amplifiers and opti-
cal module management controllers for all types of fiber optical module applications. It
also includes physical layer ICs such as 155Mbps and multi-rate (up to 2.7Gbps) CDRs
(Clock and Data Recovery), and MUX/DeMUX ICs for Access and Telecommunications
applications. This growing family of devices leads the industry in design innovation and
flexibility. The ICs often exceed stringent industry requirements.
Precision Edge
Micrel’s Precision Edge
distribution and translation, multiplexers, crosspoint switches, and high-speed gates —
all aimed at meeting the most rigorous, timing-critical applications. All Precision Edge
products are designed to provide the lowest skew and jitter IC solutions available.
Low-Dropout Voltage Regulators
Micrel has gained a reputation as a leading supplier of LDO regulators and is a major
global supplier to the mobile phone and computing industries. The Company main-
tains a very broad portfolio of LDO regulators ranging from 10mA devices in Teeny
SC-70-5 packages to 7.5A power devices and LDO controllers for even higher current
applications.
Radio Frequency Products
Micrel’s RF offering consists of two product groups: QwikRadio
mitters for actuation devices such as remote controls and remote keyless entry; and
RadioWire
industrial control and security systems.
Universal Serial Bus and PCMCIA
As a recognized leader of USB and PC Card power distribution solutions, Micrel’s
extensive selection of ICs are consistently used by many of the leading PC and
peripheral OEMs.
Hot Swap Controllers
Micrel’s hot swap power controllers support the industry requirement for high availability
(24/7/365) operation in servers, telecom and datacom equipment, and enterprise stor-
age networks. These products allow customers to upgrade or replace system boards
without having to power down the entire system. Offering products for primary- and

secondary-side applications, Micrel’s family of hot swap power controllers offers
customers a wide range of product choices uniquely suited to these applications. This
product portfolio includes the award-winning MIC2590B, the industry’s most integrated
dual-slot hot swap power controller for PCI and CompactPCI
ing Micrel’s expertise in power control and distribution, the MIC2590B was designed to
support Intel’s Itanium
dual-slot power controllers are in development. For primary-side applications, the
Company continues to add innovative products to the high-voltage hot swap product
portfolio, addressing power control applications for the telecommunications, data com-
munications, and data storage equipment markets.
MOSFET Drivers
Micrel offers a broad range of MOSFET drivers, ranging from IttyBitty
SOT-23 packaging to 12A high-power devices. “New” device families offer ther-
mally enhanced exposed pad SOIC, MSOP and space saving efficient MLF
3 x 3mm and 4 x 4mm package options.
Switch-Mode Power Supply Products
Micrel has a rapidly expanding portfolio of switching regulator products serving the mobile
device, portable computer, telecommunications and industrial markets. All products
combine Micrel’s advanced processes with the Company’s strong design expertise to
produce best-in-class products. These products address step-up, step-down and multi-
output systems, all offering designers speed and efficiency advantages.
System/Thermal Management Products
Thermal management is an increasingly critical function in today’s portable and high
performance systems. Micrel’s proprietary technology enables more functionality in smaller
packages and superior, real-world accuracy in temperature measurement via embedded
thermal diodes. Thermal diodes are increasingly used to monitor the die temperature of
high-performance integrated circuits such as Intel
Virtex
only IttyBitty
supervisor. All together, Micrel offers a complete family of one, two, and three-zone
thermal supervisor ICs as well as both analog and digital fan controllers.
Operational Amplifiers and Comparators
The Company has a broad range of high and low voltage op amps and comparators.
These ICs range from general purpose to high speed devices. Of particular note is the
MIC86x family of ICs which are, by far, the lowest power consumption op amps of their
type on the market. The advanced features of these products make them ideally suited
for all forms of battery-powered equipment.
