It drives unipolar stepper motors with a continuous output current of 1.5 A and accepts a motor supply voltage from 10 V to 60 V, making it suitable for a range of general-purpose motion-control applications like small CNC stages, 3D printer axes, and automated lab equipment. ## Microstepping and output stage The driver supports step resolutions from full-step down to 1/32 microstepping via a parallel interface, which lets the system designer trade off torque ripple and smoothness against step rate without changing the motor. The half-bridge output configuration (four bridges) drives a single unipolar stepper winding per bridge, and the Power MOSFET technology keeps conduction losses manageable at the 1.5 A continuous rating.","metaTitle":"TB67S179FTG,EL Toshiba Stepper Driver, 1.5A, 48-VQFN","metaDescription":"Toshiba TB67S179FTG,EL unipolar stepper motor driver, 1.5 A output, 10-60 V load, 1/32 microstepping, 48-VQFN.
