Texas Instruments DRV8311 3-Phase Brushless-DC Motor Driver provides three integrated MOSFET half-H-bridges for driving a three-phase brushless DC (BLDC) motor for 5V, 9V, 12V, or 18V DC rails or 1S to 4S battery-powered applications. The device integrates three current-sense amplifiers (CSA) with an integrated current-sense for sensing the three-phase currents of BLDC motors to achieve optimum FOC and current-control system implementation. The Texas Instruments DRV8311P can generate and configure PWM timers over Texas Instruments SPI (tSPI) and allows the control of multiple BLDC motors directly over the tSPI interface. This feature reduces the required I/O ports from the primary controller to control multiple motors.
