There are no phase-sequence tables, high-frequency control lines, or complex interfaces to program. Each rising edge of this signal will cause one step or microstep to be taken. This is the power input to the Easy Driver. This normally high input signal will reset the internal aolegro and disable all output drivers when pulled low.

The ASLB includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay modes. If this is not your local representative, find your local sales rep allegro. This one is complicated – please see the datasheet for more information. Connect this to the positive power supply lead.

The tabs are at ground potential and need no insulation.

We default it to slow decay mode, but you can override with your own voltage on this pin. The ASLB is a alegro microstepping motor driver with built-in translator.

Electronique/Hardware/Moteurs/Allegro A3967 – 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.

Special power-up sequencing is not required.

This should wllegro a 6V to 30V, 2A or more power supply that is clean low ripple. We’ll notify you when there are updates to this product.

These digital inputs control the microstepping mode. They are all connected together inside the board.

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.


See below diagrams for how to hook these up. Espaces de noms Page Discussion.

The translator is the key to the easy implementation of the ASLB. Menu de navigation Outils personnels Se connecter.

Allegro MicroSystems – A Microstepping Driver with Translator

This normally high input signal will minimize power consumption by disabling internal circuitry and the output drivers when pulled low.

There are no news items available for this product. This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation.

A and B are the two coils of the motor, and alegro swap the two wires for a given coil it will just reverse the direction of the motor.
