Product Summary

The TB6560AHQ/AFG is a PWM chopper-type stepping motor   driver IC designed for sinusoidal-input microstep control of   bipolar stepping motors. The TB6560AHQ/AFG can be used in   applications that require 2-phase, 1-2-phase, 2W1-2-phase and   4W1-2-phase excitation modes. The TB6560AHQ/AFG is capable   of low-vibration, high-performance forward and reverse driving of   a two-phase bipolar stepping motor using only a clock signal.

Features
