The project drives a bipolar stepper motor with the use of a dual H-bridge IS such as the SN754410. The bipolar stepper motors are usually identified on most steppers with 4 wires. Measuring the ...

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 ...

ST Micro's Markus Ekler explains the technology and derives thermal loss equations that can be used to support design decisions for stepper motor driver circuits. One constant trend in the automotive ...

The A3982 is a bipolar stepper motor drive with DMOS outputs rated at 35 V and ±1.5 A (2 A peak). Higher motor currents and reduced temperature rise come from low on resistance DMOS outputs and ...

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

The DRV8846 is a 1.4 A bipolar stepper motor driver with on-chip microstepping indexer (Step/Dir Ctrl). This device is intended for cameras, printers, projectors, and other automated equipment ...
