Texas Instruments has rolled out 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, enhanced thermal performance and high 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.
In addition to a fully protected three-phase brushless gate driver, the chip includes a 1,5 A step-down voltage regulator to power the system microcontroller (MCU), two current-sense amplifiers with integrated input and feedback resistors for current measurements, and an SPI interface for device configuration from the MCU.
The DRV8301 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 optimise performance. The IC integrates two bidirectional current-sense amplifiers, which include adjustable gain, output offset and DC calibration circuitry. The DC calibration circuitry minimises DC offset and drift over temperature to improve motor performance. The device features two-stage thermal, cycle-by-cycle over-current protection, under-voltage and shoot through protection with detailed fault feedback.
A high-current evaluation kit (DRV8301-HC-C2-KIT) is available, which 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 IDE. Multiple GUI and reference projects are available for the kit, including trapezoidal sensorless and sensorless field oriented control (FOC).
The controlCARD module included in the evaluation kit comes with TI’s new InstaSPIN-BLDC sensorless motor control solution, a back-EMF technique that allows designers to spin motors in seconds, without knowledge of motor parameters.
