Description
General part information
DRV8311 Series
The DRV8311 provides three integrated MOSFET half-H-bridges for driving a three-phase brushless DC (BLDC) motor for 5-V, 9-V, 12-V, or 18-V DC rails or 1S to 4S battery powered applications. The device integrates three current-sense amplifiers (CSA) with integrated current sense for sensing the three phase currents of BLDC motors to achieve optimum FOC and current-control system implementation.
The DRV8311P device provides capability to 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 number of required I/O ports from the primary controller to control multiple motors.
