Układ TB6600 Stepper Motor Driver

The TB6600HQ is a PWM chopper-type single-chip bipolar sinusoidal micro-step stepping motor driver. Forward and reverse rotation control is available with 2-phase, 1-2-phase, W1-2-phase, 2W1-2-phase, and 4W1-2-phase excitation modes. 2-phase bipolar-type stepping motor can be driven by only clock signal with low vibration and high efficiency.
