Three-phase brushless motor pre-driver

Texas Instruments DRV8301 brushless motor provides improved thermal performance and greater efficiency in BLDC and PMSM applications.

09/30/2011


Texas Instruments Incorporated (TI) (NYSE:TXN) introduced the first in a new line of integrated three-phase brushless motor pre-drivers. The DRV8301 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. Some examples include ventilation pumps, medical pumps, commercial refrigeration cooling systems, robotics, power tools, e-bikes and other high-torque industrial motor control applications.

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

  • 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.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
