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
• 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)
*: 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
