PWM Chopper-Type Bipolar Driver IC for Stepping Motor Control
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.
TB6560AHQ
Features
• Single-chip motor driver for sinusoidal microstep control of
stepping motors

*: These ICs are highly sensitive to electrostatic discharge. When handling them, ensure that the environment is
protected against electrostatic discharge. Ensure also that the ambient temperature and relative humidity are
maintained at reasonable level.
