Each rising edge of this signal will cause one step or microstep to be taken. This normally high input signal alllegro minimize power consumption by disabling internal circuitry and the output drivers when pulled low.

This one is complicated – please see the datasheet for more information. See below diagrams for how to hook these up. Espaces de noms Page Discussion. Connect this to the positive power supply lead.

Allegro MicroSystems – A Microstepping Driver with Translator

Connect the negative side of your power supply, as well as from any other boards you are using to drive the Easy Driver to one or more of the GND pins. Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout UVLO and crossover-current protection.


The translator is the key to the easy implementation of the ASLB. Click the image to view larger. There are no phase-sequence tables, high-frequency control lines, or complex interfaces to program.

Special power-up sequencing is not required. If this is not your local representative, find your local sales rep here. This normally high input signal will reset the internal translator and disable all output drivers when pulled low.

A and B are the two coils of the motor, and can swap the two wires for a given coil it will just reverse the direction of the 396. We default it to slow decay mode, but you can override with your own voltage on this pin.

These digital inputs control the microstepping mode. We’ll notify you when allfgro are updates to this product. By simply inputting one pulse on the STEP input the motor will take one step full, half, quarter, or eighth depending on two logic inputs.


This should be a 6V to 30V, allegor or more power supply that is clean low ripple. This is the power input to the Easy Driver. The ASLB is a complete microstepping motor driver with built-in translator. Ce site contient essentiellement des notes de travail.

The ASLB includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay modes. Menu allegr navigation Outils personnels Se connecter. Affichages Lire Voir le texte source Historique.

This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation. They are all connected together inside the board.
