Overview
The A3983SLPTR-T is a bipolar stepper motor driver from Allegro Microsystems, housed in a 24-pin TSSOP-EP package. It supports step resolutions of 1, 1/2, 1/4, and 1/8 microstepping with an integrated translator. The device operates on a logic supply voltage of 3V to 5.5V and drives loads between 8V and 35V. It delivers a maximum output current of 2A per phase using DMOS technology. The junction temperature range spans from -20°C to 150°C.
Feature Summary
- Integrates a full bridge driver with a built-in translator for simplified control interface requirements.
- Supports multiple step resolutions including full, half, quarter, and eighth microstepping modes.
- Features overcurrent protection and thermal shutdown mechanisms for enhanced operational reliability.
Applications
- General purpose bipolar stepper motor control
- Motion control systems requiring microstepping precision
- Industrial automation actuators
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm that the TSSOP-EP package requires appropriate PCB footprint design for the exposed pad thermal dissipation. Ensure logic voltage levels match the 3V to 5.5V input specification for reliable interfacing.
Selection Notes
Select this component for applications requiring up to 2A output current with bipolar stepper motors. It is suitable where space constraints favor a 24-pin TSSOP package. Consider the 1/8 microstepping capability for smooth motion control needs. Verify load voltage does not exceed 35V to prevent device damage.
Part Context
This part belongs to the A3983 series of microstepping drivers. It shares functional similarities with other Allegro bipolar drivers but is distinct in its 2A current rating and specific 24-pin TSSOP-EP form factor. It serves as a complete solution combining control logic and power stages.
Replacement Considerations
The A3987SLPTR-T offers similar functionality but supports higher load voltages up to 50V and includes 1/16 microstepping resolution. Check if the increased voltage tolerance or finer resolution is required for the specific application before substituting.
