In summary, this presentation has introduced the L6470 stepper motor controller/driver IC. The L6470 includes a digital core that controls the motion profile along with the power bridges and the microstepping controller. The advantages of the L6470 include simplified design, reduced loading on the microcontroller, and smoother operation for the motor. It communicates with the microcontroller using an SPI interface. Configuration information and movement commands are sent to the L6470 across the SPI and the device sends status and fault information back to the microcontroller. A key feature of the L6470 is the dSpin core that implements a motion control algorithm in the dedicated state machine.
