Introduction:
An electric motor has a stator and a rotor. Both are electrically/magnetically
induced to produce magnetic fields either through current
fed coils or permanent magnets. The combination of repulsive
and attractive magnetic fields across stator and rotor help
the motor to convert fed-electrical power into rotational
mechanical energy. In the traditional DC motors, the electrical
energy is fed to the rotor (two power the copper coils)
via a conducting carbon brush, which is pressed on to the
metal leads on the rotor.
The drawback of brush-based motors is they produce electric-sparks
resulting in electromagnetic noise and also requires maintenance.
The electronic systems such as computers and such electro
magnetic noise (EMI) sensitive devices are susceptible to
noise produced by brushed motors.
Brushless DC (BLDC) Motor operates with a controller via
electronic communication. BLDC motors rely on a combination
of sensors, magnets, and electronic devices to switch winding
current. The electronics devices together does the same
function as mechanical commutators used on standard DC motors,
but without physical contact and hence they are frictionless,
clean with no carbon dust, quiet in terms of electrical
noise and maintenance free.
So BLDC motors need semiconductor ICs. Here in this article
we provide you with list of some latest ICs for your brushless
DC motor control circuit design. Before selecting the IC

Product Highlights:
TI's new device DRV8301, an integrated three-phase brushless
motor pre-drivers, can drive sub-10-A to 60-A external FETs,
provides current scalability, improved thermal performance
and efficiency in brushless DC (BLDC).
SPI-6631M, a new 3-phase brushless motor driver from Sanken
Electric is a 3-phase brushless DC motor driver. SPI-6631M
integrates a pre-drive circuit and output elements (6 MOSFETs)
on a single chip through the use of BCD process technology,
and by using a compact surface mounting package.
The all-in-one motor controller IC from Diodes Inc for single-coil
low-power brushless DC fans and motors features necessary
drive, protection and interface functionality, the SOT89-5L
packaged AH5798 is suitable for small fan and motor applications,
including cooling fans for netbooks and notebooks.
AH5798 Integrates a full-bridge driver featuring soft switching,
the controller requires no external driver components but
supports average source and sink currents up to 300mA. AH5798
has built-in Hall sensor and amplifier.
Holtek's HT45FM2C is suitable for three phase brushless
DC motor fan applications.
KMZ60, a magnetoresistive angle sensor with integrated
amplifier IC from NXP Semiconductors N.V. targets device
includes electronic power steering (EPS) or window wiper
systems in cars and also to control BLDC motors in industrial
applications.
Toshiba's newly developed TB6586FG/AFG motor controller
IC has a 150°-turn-on angle and employs a lead angle
control function that sets the optimum turn-on point to
enable highly efficient driving of three-phase brushless
motors.
