PWM Chopper-Type Bipolar Driver IC TB6560AHQ

Description

The TB6560AHQ is a PWM chopper-type bipolar stepping motor driver IC designed for micro stepping control of two-phase bipolar stepper motors. It integrates power stages and control logic to drive motor coils efficiently with reduced vibration and smooth motion based on a sinusoidal micro step input. It supports multiple step excitation modes (2-phase, 1-2-phase, 2W1-2-phase, 4W1-2-phase), and can perform forward and reverse rotation with only a clock input command for motion control.
