A3967: Microstepping Driver with Translator

Espaces de noms Page Discussion. They are all connected together inside the board. This normally high input signal will minimize power consumption by disabling internal circuitry and the output drivers when pulled low. Click the image to view larger. 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 allegeo when pulled low. This should be a 6V to 30V, 2A or more power supply that is clean low ripple.


The tabs are at ground potential and need no insulation. The translator is the key to the easy implementation of the ASLB. Connect the negative side of your power supply, as well as from any other boards you are using to drive the Easy Zllegro to one or more of the GND pins.

This one is complicated – please see the datasheet for more information. Each rising edge of this signal will cause one step or microstep to be taken. The ASLB includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay modes.

Connect this to allegr positive power supply lead. There are no news items available for this product. Menu de navigation Outils personnels Se connecter. 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 is the power input to the Easy Driver. Alletro Lire Voir le texte source Historique. Ce site contient essentiellement des notes de travail. We’ll notify you when there are updates to this product.


This needs to be a 0V to 5V or 0V to 3. There are no phase-sequence tables, high-frequency control lines, or complex interfaces to program. Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout UVLO and crossover-current protection.

Allegro MicroSystems – A Microstepping Driver with Translator

See below diagrams for how to hook these up. We default it to slow decay mode, but you can override with your own voltage on this pin. This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation.

Special power-up sequencing is not required. The ASLB is a complete microstepping motor driver with built-in translator. These digital inputs control the microstepping mode. A and Alletro 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.
