Allegro A3967 Motor Driver (stepper) Module max. 30V 0.75A

Description

The A3967 Motor Driver is a complete “micro-stepping” motor driver with a built-in translator. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and eighth-step modes, with an output drive capability of 30 V and 750 mA. The A3967SLB includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current decay modes.

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

The translator is the key to the easy implementation of the A3967 Motor Driver. 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).

There are no phase-sequence tables, high-frequency control lines, or complex interfaces to program. The A3967SLB interface is an ideal fit for applications where a complex Program is unavailable or over-burdened.

Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO) and crossover-current protection.

Special power-up sequencing is not required.
