DRV8308 Brushless DC Motor Controller
Texas Instruments DRV8308 Brushless DC Motor Controller is a three half-bridge pre-driver that drives up to 130mA to six N-type MOSFETs with a single power supply. This pre-driver features a configurable digital speed loop, speed controls, and commutation modes to optimize motor performance in sensored three-phase brushless DC motors. When properly tuned, the Texas Instruments DRV8308 can drive motors with less than 0.1% cycle jitter and fast torque compensation. The integrated digital speed loop allows the motor to maintain speed under variable loads with programmable gain and loop filters. The adjustable slew rates can also lower the switching noise and improve EMC. The DRV8308 device also supports both the 120° and 180° commutation modes with the ability to adjust the delay to increase power efficiency. For high-performance systems, sinusoidal (180°) commutation mode is used to minimize acoustic noise and torque ripple. Jitter caused by non-ideal Hall placement and matching can be eliminated once constant speed is reached by switching from three Hall sensor phases to just a single Hall sensor.
