TB6560AHQ Stepper Motor Driver IC

TB6560AHQ Stepper Motor Driver IC

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:
Ron (upper and lower sum) =
TB6560AHQ: 0.6 Ω (typ.)
TB6560AFG: 0.7 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 = TB6560AHQ: 3.5 A (peak)
TB6560AFG: 2.5 A (peak)
• Packages: HZIP25-P-1.27
HQFP64-P-1010-0.50
• 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)
