A3983SLP Description

Short technical summary and product information.

The A3983SLP from Allegro Microsystems is a fully integrated DMOS microstepping motor driver designed for easy operation of bipolar stepper motors. It supports full, half, quarter, and eighth-step modes, offering precise control.

 

This driver features an output drive capacity of up to 35 V and ±2 A. It includes a fixed off-time current regulator with automatic selection between Slow and Mixed decay modes, which helps reduce audible motor noise and power dissipation. The integrated translator simplifies implementation, requiring only a single STEP input pulse for microstepping, making it suitable for applications with limited microprocessor resources.

 

Key electrical features include low RDS(ON) outputs, synchronous rectification for low power dissipation, internal UVLO, and thermal shutdown circuitry. Crossover-current protection is also built-in. The A3983SLP is supplied in a 24-pin TSSOP with an exposed thermal pad (suffix LP), designed for surface mounting.

 

This component is ideal for general-purpose applications where efficient and accurate stepper motor control is required. Its integrated nature and simplified interface reduce design complexity.
