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.
