The SLA7070MPRT series are unipolar two-phase stepper motor driver integrated circuits (ICs). This device uses a clock input method as a control signal input method, enabling full control of the ...

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 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 ...

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 would ...

Higher-than-normal operating voltages give steppers better torque at high speeds — but watch that current! • The inductance in a stepper-motor phase winding limits how fast current rises when power is ...

You probably know that if you spin a motor (mechanically) it generates electricity on what would normally be the inputs. This can be a problem when you shut off a spinning motor and is the reason that ...
