A3984SLP

Overview

The A3984SLP is a fully integrated bipolar stepper motor driver manufactured by Allegro Microsystems. It operates with a logic supply voltage range of 3V to 5.5V and supports load voltages from 8V to 35V. The device features an output current capacity of 2A and utilizes DMOS technology. It is housed in a 24-pin TSSOP package with an exposed pad, measuring 7.8mm x 4.4mm x 1.05mm. The component supports step resolutions of 1, 1/2, 1/4, and 1/16 microstepping. It functions within a junction temperature range of -20°C to 150°C.

Feature Summary

Fully integrated control and power stage for bipolar stepper motors
Supports multiple step resolutions including full, half, quarter, and sixteenth microstepping
Built-in fixed off-time current regulator for consistent torque performance

Applications

General purpose motion control systems
Office automation equipment
Industrial process control devices

Procurement Notes

Verify the specific suffix of the part number during procurement. The base model A3984SLP indicates a tube package, while variants like A3984SLPTR-T use tape and reel packaging. Confirm availability status as this specific part number may be discontinued or subject to change. Ensure the selected variant matches the required packaging format for the assembly line.

Selection Notes

Select this component for applications requiring a single-chip solution for bipolar stepper motors with moderate current demands up to 2A. It is suitable for low-voltage logic interfaces (3V-5.5V). Consider thermal management requirements due to the exposed pad design. Verify that the load voltage does not exceed 35V and that the operating environment stays within the specified temperature range.

Part Context

The A3984SLP belongs to the Allegro A398x series of stepper motor drivers. This family provides complete drive solutions for bipolar stepper motors, integrating logic, current regulation, and protection circuits. The device is designed to simplify system design by reducing the number of external components required compared to discrete driver implementations.
