Two-chip designs combining a microcontroller or DSP with a highly integrated driver IC simplify the design of a stepper-motor controller, while also enabling sophisticated control features that ...

3.4 Stepper Motor Controller Stepper motors are useful for relatively low-speed, intermediate-torque drive and positioning applications, particularly where accurate sub-revolution rotor position ...

This unipolar stepper motor driver circuit is used to drive a 12V unipolar stepper motor with a current rating of 1.25A. It uses PCA9537 IC, which is a 10-pin CMOS device that provides 4 bits of ...

Rather than having the host Pi communicate directly with the stepper drivers, the 3+Pi features an onboard STM32F302CBT6 that handles the actual motor control. The Pi just needs to tell it what to ...

Even first-time users can get a stepper motor moving as commanded in 30 min or less. Commands can be issued from any serial terminal program or from the EZ Stepper Windows program, but the EZHR17EN ...

For applications where the microprocessor is overburdened or absent, the SLA7051M constant-current, two-phase unipolar stepper motor driver includes a built-in translator, allowing ...

Toshiba Electronics Europe has introduced the TB67S559FTG 50V/3.0A stepper motor driver IC that supports constant current control with built-in current detection.

Toshiba has launched an 4 x 4mm QFN24 stepper motor driver that can run from 4.5 to 33V and deliver up to 1.2A. Typical on-resistance of the output block is 1.2Ω. “It is well suited for ...

For each application the right type of stepper motor and driving circuit has to be determined, of course, as they also have many reasons why you’d not want to use them, or just a particular type.
