A3950SEUTR-T

Overview

The A3950SEUTR-T is a full-bridge MOSFET driver manufactured by Allegro Microsystems, designed for brushed DC motor control applications. It operates within a supply voltage range of 8 V to 36 V and supports a maximum output current of 2.8 A. The device features an integrated power stage with low on-resistance DMOS transistors. It is housed in a QFN-16 surface-mount package suitable for automated assembly. The component functions across an operating temperature range from -20 °C to +85 °C.

Feature Summary

• Integrates a complete H-bridge power stage with dedicated control logic for simplified system design
• Provides parallel interface inputs for direct connection to microcontrollers or logic circuits
• Includes built-in protection mechanisms against overcurrent conditions and thermal overload

Applications

• Brushed DC motor speed and direction control in industrial automation equipment
• Motor drive circuits for automotive accessory systems such as window lifts or wipers
• General-purpose motion control modules requiring compact form factor solutions

Procurement Notes

Verify the specific suffix 'SEUTR' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure that the ordering documentation explicitly references the Allegro MicroSystems part number to avoid confusion with similar variants in the A3950 family. Cross-reference the RoHS status and environmental compliance data provided in the latest product specification before finalizing procurement orders.

Selection Notes

Select this component when a fully integrated solution for medium-power brushed DC motors is required. The 2.8 A continuous current rating suits applications not demanding high-torque performance. Consider the QFN-16 package for space-constrained PCB layouts. Evaluate thermal management requirements based on the specified junction temperature limits and ambient operating conditions defined in the electrical characteristics table.

Part Context

This part belongs to the A3950 series of motor drivers developed by Allegro MicroSystems. The series focuses on providing cost-effective, high-performance solutions for various motor control tasks. The A3950SEUTR-T variant specifically utilizes a QFN-16 package, distinguishing it from other pin-compatible options like TSSOP versions. It represents a standard offering for general-purpose motor driving needs within the company's portfolio.
