Features:
PWM chopper-type bipolar stepping motor driver IC
TB6600HQ / HG is a single-chip PWM bipolar sinusoidal chopper type stepper motor micro step driver.
Can control 2-phase stepper motor in forward and reverse rotation
With a 1-2, W1 -2 phase 2W1 -2 phase, 4W1 -2-phase excitation mode.
Just a clock signal can drive two-phase bipolar stepper motor to achieve low vibration, high efficiency work.
Single-chip bipolar sinusoidal micro step motor driver
5 kinds of sub-modes can be selected (1/1, 1/2, 1/4, 1/8, 1/16 step)
With reset and enable pins, With standby function
Break the traditional single-supply operation
