TB6560AHQ stepper motor driver

Description

The TB6560AHQ is a PWM chopper-type stepping motor driver IC designed for sinusoidal-input microstep control of bipolar stepping motors. The TB6560AHQ can be used in applications that require 2-phase, 1-2-phase, 2W1-2-phase and 4W1-2-phase excitation modes. The TB6560AHQ 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

• High output withstand voltage due to the use of BiCD process: Ron (upper and? lower sum) = 0.6 Ω (typ.)

• Forward and reverse rotation

• Selectable phase excitation modes (2, 1-2, 2W1-2 and 4W1-2)

• High output withstand voltage: VDSS = 40 V

• High output current: IOUT = AHQ: 3.5 A (peak)

• Packages: HZIP25-P-1.27

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

• Output monitor pin: MO current (IMO (max) = 1 mA)

• Reset and enable pins

• Thermal shutdown (TSD)
