PWM Chopper-Type bipolar Stepping Motor Driver IC
TB6600HQ
The TB6600HQ is a PWM chopper-type single-chip bipolar sinusoidal micro-step stepping motor driver. Forward and reverse rotation control is available with 2-phase, 1-2-phase, W1-2-phase, 2W1-2-phase, and 4W1-2-phase excitation modes. 2-phase bipolar-type stepping motor can be driven by only clock signal with low vibration and high efficiency.

• Output current: IOUT = 5.0 A (absolute maximum ratings, peak, within 100ms)
IOUT = 4.5 A (operating range, maximal value) • Packages: HZIP25-1.00F
• Built-in input pull-down resistance: 100 kΩ (typ.)
The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded, even for a moment. Do not exceed any of these ratings. Exceeding the rating (s) may cause the device breakdown, damage or deterioration, and may result injury by explosion or combustion. Please use the IC within the specified operating ranges.
