DALLAS, Sept. 9, 2011 /PRNewswire/ -- Texas Instruments
Incorporated (TI) (NYSE: TXN) today introduced the first in a new
line of integrated three-phase brushless motor pre-drivers. The
DRV8301 is the most highly integrated pre-driver available today,
reducing board space as much as 60 percent compared to the next
closest integrated solution. It can drive sub-10-A to 60-A external
FETs, providing current scalability, improved thermal performance
and greater efficiency in brushless DC (BLDC) and permanent magnet
synchronous motor (PMSM) applications, such as ventilation pumps,
medical pumps, commercial refrigeration cooling systems, robotics,
power tools, e-bikes and other high-torque industrial motor control
applications. For more information or to place an order, visit
www.ti.com/drv8301-pr.
The highly integrated DRV8301 reduces board space, bill of
materials and system complexity while improving reliability. In
addition to a fully protected three-phase brushless gate driver, it
includes a 1.5-A step-down voltage regulator to power the system
microcontroller (MCU), such as the C2000™ Piccolo™; two
current-sense amplifiers with integrated input and feedback
resistors for current measurements; and a SPI interface for device
configuration from the MCU.
Key features and benefits
- Three-phase brushless gate driver: Provides gate drive
current up to 1.7-A source and 2.3-A sink from a single 8-V to 60-V
supply. Slew rate and dead-time can be adjusted to optimize
performance.
- 1.5-A step-down voltage regulator: Operating from 3.5 V
to 60 V, the regulator provides power for the MCU or other system
components.
- Two bi-directional current-sense amplifiers: Includes
adjustable gain, output offset and DC calibration circuitry to
reduce board space and system cost. The DC calibration circuitry
minimizes DC offset and drift over temperature to improve motor
performance.
- Fully protected: Two-stage thermal, cycle-by-cycle over
current protection, under-voltage, and shoot through protection
with detailed fault feedback reduces design complexity and improves
system reliability.
Tools and support
A high-current evaluation kit (DRV8301-HC-C2-KIT) is available
today for a suggested retail price of $299. The kit includes the DRV8301 motor driver,
a 32-bit C2000™ Piccolo™ MCU controlCARD module, a quick-start
graphical user interface (GUI), full development source code and
Code Composer Studio™ (CCStudio) integrated development environment
(IDE). Multiple GUI and reference projects are available for the
DRV8301-HC-C2-KIT, including trapezoidal sensorless and sensorless
field oriented control (FOC).
The 32-bit C2000 Piccolo MCU controlCARD module included in the
DRV8301 evaluation kit comes with TI's new InstaSPIN™-BLDC
sensorless motor control solution, a unique back-electromagnetic
field (EMF) technique that allows designers to spin motors in
seconds, without knowledge of motor parameters.
Engineers can ask questions and help solve problems in the Motor
Drivers Forum in the TI E2E™ Community.
Package, availability and pricing
The DRV8301 is available today in a 14-mm x 8.1-mm HTSSOP
package for a suggested retail price of $2.50 for 1,000 units. For simpler hardware-based
device configuration, the DRV8302 integrated three-phase brushless
motor pre-driver will be available in 3Q 2011.
