L6470 dSPIN Motor Driver

L6470 dSPIN Motor Driver

The L6470 dSPIN motor driver from STMicroelectronics provides fully digital motion control with no need for a dedicated MCU to perform speed profile and positioning calculations. The digital control core, together with the innovative voltage-mode driving operation, results in a position resolution of up to 128 micro-steps and smoother motion. The fast SPI interface, with daisychain capability, allows a single MCU to control multiple devices. Reduced resonance, noise and vibration at low speed make the overall application much simpler and lighter.
