Stepping Motor Driver IC
TB6608FNG
The TB6608FNG is a PWM constant-current type stepping
motor driver IC designed for sinusoidal-input micro-step control of
stepping motors.
The TB6608FNG can be used in applications that require
2-phase, 1-2-phase, W1-2-phase and 2W1-2 phase excitation
modes. The TB6608FNG is capable of forward and reverse driving
of a 2-phase bipolar stepping motor using only a clock signal.
Features
• Motor power supply voltage: VM = 15 V (max)
Weight: 0.09 g (typ.)
• Control power supply voltage: VCC = 2.7 to 6 V
• Output current: Iout ≤ 0.8 A (max)
• Output ON-resistance: Ron = 1.5 Ω (upper and lower sum@VM = 5 V)
• Decoder that enables microstep control with the clock signal
• Selectable phase excitation modes (2, 1-2, W1-2 and 2W1-2)
• Internal pull-down resistors on inputs: 200 kΩ (typ.)
• Output monitor pin ( MO )
• Thermal shutdown (TSD) and undervoltage lockout (UVLO) circuits
• Small surface-mount package (SSOP20: 0.65 mm lead pitch)
• This product has a MOS structure and is sensitive to electrostatic discharge. When handling this product, ensure
that the environment is protected against electrostatic discharge by using an earth strap, a conductive mat and an
ionizer. Ensure also that the ambient temperature and relative humidity are maintained at reasonable levels.
• Do not insert devices in the wrong orientation or incorrectly. Otherwise, it may cause the device breakdown,
damage and/or deterioration.
