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. This one is allegrk – please see the datasheet for more information. We’ll notify you when there are updates to this product.

Allegro MicroSystems – A Microstepping Driver with Translator

Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout UVLO and crossover-current protection. This normally high input signal will reset the internal translator and disable all output drivers when pulled low. Click the image to view larger.


Each rising edge of this signal will cause one step or microstep to be taken. Menu de navigation Outils personnels Se connecter.

They are all connected together inside the board. If this is not your local representative, find your local sales rep here.

This is the power input to the Easy Driver. Connect this to the positive power supply lead. Ce site contient essentiellement des notes de travail.

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.

The tabs are at ground potential and need no insulation. This needs to be a alletro to 5V or 0V to 3. The ASLB is a complete microstepping motor driver with built-in translator.

There are no news items available for this product. The translator is the key to the easy implementation of the ASLB.

The ASLB includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay modes. 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 normally high input signal will minimize power consumption by disabling internal circuitry and the output drivers when pulled low.


These digital inputs control the microstepping mode. 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 allevro.

There are no phase-sequence tables, high-frequency control lines, or complex interfaces to program. This should be a 6V to 30V, 2A or more power supply that is clean low ripple. Affichages Lire Voir le texte source Historique.
