A4956GESTR-T

Overview

The A4956GESTR-T is a fully integrated brushless DC motor driver manufactured by Allegro MicroSystems. It operates within a supply voltage range of 5.5V to 50V and utilizes NMOS technology. The device is housed in a 20-WFQFN exposed pad package (4x4mm) designed for surface mount installation. Key functional capabilities include commutation control, direction management, and an output configuration featuring two half-bridge pre-drivers. It supports AC/DC brushed motors and functions across a temperature range of -40°C to 105°C.

Feature Summary

Integrates commutation logic and direction management for simplified system design
Features dual half-bridge pre-driver outputs for driving external power stages
Supports parallel interface communication for flexible control integration

Applications

Brushed DC motor control systems
General purpose motion control applications
Industrial automation equipment requiring integrated driver solutions

Procurement Notes

Verify the specific suffix 'GESTR-T' to confirm the 20-QFN-EP package and tape-and-reel packaging format. Ensure compatibility with the 5.5V to 50V operating voltage range required by the target application. Confirm that the parallel interface protocol matches the host controller's capabilities before finalizing procurement specifications.

Selection Notes

Select this component when a compact solution for brushed DC motor control is required. The 20-WFQFN package offers a small footprint suitable for space-constrained designs. Verify that the system voltage remains within the 5.5V to 50V limits and that the thermal environment stays within the -40°C to 105°C operational range for reliable performance.

Part Context

This part belongs to the A4956 series from Allegro MicroSystems, which focuses on integrated motor driver solutions. The series provides combined logic and power stages to reduce external component count. The A4956GESTR-T specifically denotes the QFN package variant intended for high-density surface mount assembly in modern electronic devices.
