DIODES INCORPORATED’S PRODUCTS ARE DESIGNED FOR HIGH PERFORMANCE,
ACROSS A WIDE RANGE OF EXISTING AND EMERGING APPLICATIONS
COMPANY OVERVIEW
Diodes’ Hall Effect Sensors and Motor Control
Diodes Incorporated is a leading
global provider of Discrete, Logic,
and Analog semiconductors.
Diodes offers a wide and comprehensive
product line for Hall Effect switching and
Brushless Direct Current (BLDC) fan and
motor applications. Combining its
superior Hall Effect technology, extensive
analog design expertise, leading package
technology and manufacturing capability,
Diodes can offer the outstanding system
solutions across numerous applications.
Its global footprint includes sales
offices in 5 countries and
manufacturing locations in China,
Europe and the USA.
A focus on product
innovation, cost
reduction, acquisitions
and customer service
has made Diodes
Incorporated an
industry leader.
Combining leading silicon and
packaging technologies, Diodes
provides a broad portfolio of
Discrete semiconductors
comprising Bipolar Transistors,
MOSFETs, Schottky diodes, SBR,
switching diodes and functional
specific arrays to enable our
customers’ next generation designs.
The Diodes' Analog IC portfolio
consists of 6 main areas: Power
Management ICs, Standard Linear,
Lighting, Sensors, Direct Broadcast
by Satellite and Applications
Specific Standard Products.
Hall Effect Switch ICs
Hall Effect switch ICs provide simple and
reliable solutions to contactless switching.
They are used in many application areas
from open and close detection to rotation
and flow monitoring. Using core
architectures based on a stable patented
Hall Effect plate design, Diodes provides
three comprehensive Hall Effect switch
product families: Omnipolar, Unipolar and
Latched Hall Effect switches.
The Diodes’ Hall Effect switch portfolio is
well suited to meeting the requirements of:
Cell phones
Portable PCs
Still and video cameras
Metering
Motor commutation
Rotation detection
Level detection
Contactless switching
All the Diodes’ Hall Effect switches are
designed with the end application in mind,
enabling highly effective system solutions
through wide operating ranges, various
operate and release points, and ultra small
and low profile packaging.
DC Fan and Motor Control
An intelligent approach to electronic
system cooling is important. Air movement
needs to be optimized, power consumption
needs to be closely controlled and the
audible noise and electromagnetic
interference a motor generates needs to
be kept to a minimum.
Diodes offers four controller families and a
range of Hall Effect Latches which provides
an effective solution to brushless DC fans,
motors, blowers and pumps. Ranging from
the highly integrated but simple to use
“all-in-one” products to the flexible feature
rich pre-drivers, the product line suits a
wide range of applications from netbooks,
notebooks, instrumentation, desktop PCs,
servers, cooling of LED light engines to
industrial pumps and blowers.
Diodes fully supports the BLDC motor
and fan market with Hall Effect drivers and
pre-drivers, complemented by world class
Bipolar transistors, MOSFETs, full bridge
and half bridges, gate drivers and current
monitors.

Anisotropic magnetoresistive (AMR) sensors are created from thin permalloy strips to form a Wheatstone bridge where the output
voltage is proportional to the magnetic field component Hy. An auxiliary magnetic field, Hx, perpendicular to Hy is necessary to bias the
sensor into its linear region. Sensors with a single Wheatstone bridge are available with or without an internal auxiliary magnet for the
Hx field bias. The number of sensors required is dependant on the application; proximity and magnetic sensing only requires one
sensor where as linear and angular position sensing requires two sensors to provide the necessary output signals.

The ZXBM single phase pre-driver family provides a flexible, high performance and feature rich solution for BLDC motor, fan and blower
applications. An internally generated Hall bias allows direct connection to an external Hall element catering to different sensitivity
requirements. The internal output drive allows the external power stage to be a full bridge, two half bridges or a discrete solution using
Bipolar transistors or MOSFETs to achieve higher power performance over a variety of supply ranges.
