There are no news items available for this product. These digital inputs control the microstepping mode. This one is complicated allwgro please see the datasheet for more information.

A3967: Microstepping Driver with Translator

The ASLB includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay modes. Special power-up sequencing is not required. See below diagrams for how to hook these up. Each rising edge of this signal will cause one step or microstep to be taken. Connect this to the positive power supply lead.


Ce site contient essentiellement des notes de travail. The translator is the key to the easy implementation of the ASLB.

The tabs are at ground potential and need no insulation. Menu de navigation Outils personnels Se connecter. This needs to be a 0V to 5V or 0V to 3.

Electronique/Hardware/Moteurs/Allegro A3967 – EasyDriver

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 motor. This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation.

Espaces de noms Page Discussion. This normally high input signal will minimize power consumption by disabling internal circuitry and the output drivers when pulled low. 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 allegto GND pins.

Electronique/Hardware/Moteurs/Allegro A – EasyDriver —

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, 2A or more power supply that is clean low ripple.


The ASLB is a complete microstepping motor driver with built-in sllegro. Click the image to view larger. They are all connected together inside the board.

Allegro MicroSystems – A Microstepping Driver with Translator

This normally high input signal will reset the internal translator and disable all output drivers when pulled low. There are no phase-sequence tables, high-frequency control lines, or complex interfaces to program.

Affichages Lire Voir le texte allegrl Historique. We default it to slow decay mode, but you can override with your own voltage on this pin.

Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout UVLO and crossover-current protection. This is the power input to the Easy Driver.
