Overview
The A3959SLBTR-T is a fully integrated brushed DC motor driver manufactured by Allegro Microsystems. It operates with a supply voltage range of 4.5V to 5.5V and supports load voltages from 9.5V up to 50V. The device delivers an output current of 3A and utilizes DMOS technology. It features a parallel interface and is housed in a 24-SOIC package. The component functions as a dual half-bridge driver, integrating both control logic and power stages for efficient motor management.
Feature Summary
- Integrates full control and power stages for simplified design
- Supports high-voltage loads up to 50V
- Utilizes DMOS technology for robust performance
Applications
- Brushed DC motor control
- General-purpose motion applications
- Ignition systems
Procurement Notes
Verify the specific suffix against official documentation, as 'A3959SLBTR' without the trailing '-T' may indicate tube packaging or a discontinued variant. Confirm RoHS compliance status, as some versions are marked non-compliant. Ensure the selected package matches the required PCB footprint and thermal dissipation needs for the target application.
Selection Notes
Select this component when a single-chip solution for medium-current brushed DC motors is required. It is suitable for designs needing a 3A drive capability within a compact SOIC form factor. Consider the parallel interface requirements and ensure the system logic levels align with the driver's input specifications for reliable operation.
Part Context
This part belongs to the A3959 series of motor drivers from Allegro MicroSystems. It is designed to replace discrete solutions by combining gate drivers, protection circuits, and logic into one IC. The series targets cost-sensitive applications requiring reliable motor control without complex external component counts.
Replacement Considerations
The A3958SLBTR-T is listed as a similar alternative. Verify pin compatibility and current ratings before substitution. Check if the serial interface of the A3958 meets the system requirements compared to the parallel interface of the A3959.
