TB6560AHQ, TB6560AFG

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.

Features

• Single-chip motor driver for sinusoidal microstep control of

stepping motors

• High output withstand voltage due to the use of BiCD process:

• Internal pull-down resistors on inputs: 100 kΩ (typ.)

• Reset and enable pins

• Thermal shutdown (TSD)

*: 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.
