Instead of messin’ with an ULN2007, you just use any of the bipolar stepper motor IC’s, any 3D printer PCB, possibly with those “step stick” driver boards. And bipolar has many advantages: 1.

For each application the right type of stepper motor and driving circuit has to be ... Trinamic TMC2130 stepper motor driver, ... Tagged A4988, bipolar stepper motor, DRV8825, laser ...

The DSC4020 bipolar chopper drive is designed for development projects — just connect a single power supply and motor and the drive is ready to run.

Toshiba Electronics Europe has launched a bipolar, 2-channel stepping motor driver rated for a high voltage of 40V and currents of up to 2.0A. The TC78S122FNG has been designed to save space, reduce ...

The Toshiba TC78H670FTG two-phase, bipolar, stepper-motor driver removes the need for any external current-sense resistor by incorporating on-chip current detection. It’s often desirable or even ...

Allegro MicroSystems has unveiled a 40 V motor driver IC capable of driving one stepper motor and one DC motor. The bipolar stepper driver outputs are rated up to 1.6 A and the high current DC driver ...
