TB6600HG
PWM Chopper-Type bipolar
Stepping Motor Driver IC
The TB6600HG 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.

Ta = 25°C, with infinite heat sink.
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.

The maximum current of the operating range can not be necessarily conducted depending on various
conditions because output current is limited by the power dissipation Pd.
Make sure to avoid using the IC in the condition that would cause the temperature to exceed Tj (avg.)
