TB67S Stepper Driver

 NOTE: this driver is sold everywhere as TB6600 which is not true, this driver use TOSHIBA TB67S109AFTG chip (see download tab to check TB67S109AFTG  data sheet). By technical and electrical characteristics it has a lot of similarities with TB6600 and both models are made by TOSHIBA .

  SIMPLE Wiring Diagram

  BASIC Description

TB67S109AFTG is 2nd generation PWM chopper-type single-chip bipolar sinusoidal micro-step stepping motor driver. This 4A drive is better than HY-268N-DIV-5A stepper drive. This 2-phase bipolar-type stepping motor can be driven by only clock signal with low vibration and high efficiency and low heat generation. Suitable for drive Two-phase stepping motor dynamic voltage 9V to 40V, the maximum drive current is less than 4A.

This drive uses the current loop subdivision control, the motor torque ripple is very small, low-speed running is very smooth. High-speed torque is much higher than other two-phase drives, high positioning accuracy. Widely used in the engraving machines, CNC machine tools, packaging machinery and other high resolution requirements on the device. NEMA17, NEMA23, NEMA24 and NEMA34 stepper motors work perfectly with this 4A Stepper Driver.
