A3967SLBTR-T

Overview

The A3967SLBTR-T is a dual full-bridge microstepping motor driver with an integrated translator, manufactured by Allegro MicroSystems. It operates within a supply voltage range of 4.75 V to 30 V and supports load voltages up to 30 V. The device delivers an output current of 750 mA per channel with a typical quiescent supply current of 5 mA. Designed for surface-mount installation, it is housed in a 24-pin SOIC package. The component functions reliably across an operating temperature range from -20°C to +85°C.

Feature Summary

• Integrates a microstep translator to simplify control interface requirements
• Features dual full-bridge architecture for bipolar stepper motor drive
• Includes built-in current regulation and thermal shutdown protection

Applications

• Bipolar stepper motor control systems
• Precision motion control applications
• Automotive instrumentation actuators

Procurement Notes

Verify the complete part number including the trailing suffix to ensure correct packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check humidity sensitivity levels and storage conditions to maintain component integrity during assembly processes.

Selection Notes

Select this component when a single-chip solution for microstepping is required without external logic translators. Ensure the 750 mA output capability meets the specific motor coil current demands. Verify that the 24-pin SOIC footprint aligns with the target PCB layout constraints and thermal management strategy.

Part Context

This device belongs to the A3967 series of motor drivers designed for low-power bipolar stepper applications. It distinguishes itself by combining power switching with digital translation logic, reducing system complexity compared to drivers requiring separate step/direction controllers.
