A1441EELLT-T

Overview

The A1441EELLT-T is a fully integrated motor driver IC from Allegro MicroSystems, designed for brushless DC (BLDC) applications. It utilizes Bi-CMOS technology and features an open/switch interface with two half-bridge outputs capable of delivering up to 150mA. The device operates within a supply voltage range of 2V to 4V and supports junction temperatures from -40°C to 165°C. Packaged in a compact 6-MLP/DFN (2x2) surface-mount format, it integrates both control logic and power stages.

Feature Summary

• Fully integrated design combining control and power stages
• Optimized for brushless DC motor applications
• High thermal tolerance supporting extended temperature ranges

Applications

• Haptic feedback systems
• Brushless DC motor control
• Vibration generation modules

Procurement Notes

Verify component authenticity through authorized channels due to the part's discontinued status. Confirm that the specific package variant matches the required footprint for PCB integration. Ensure compliance with RoHS3 standards as documented. Request official datasheets to validate electrical characteristics against system requirements before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring low-voltage operation between 2V and 4V. The integrated nature reduces external component count compared to discrete solutions. Consider the high junction temperature rating for environments with limited cooling. Verify that the 150mA output current meets the load requirements of the target motor or actuator.

Part Context

This device belongs to Allegro's portfolio of intelligent motor drivers. It complements other magnetic sensing and power management solutions offered by the manufacturer. The product line focuses on simplifying motion control architectures through highly integrated semiconductor solutions suitable for consumer and industrial electronics.

Replacement Considerations

The manufacturer lists this part as discontinued. No public substitute part numbers are confirmed in the provided documentation. Designers should evaluate alternative BLDC drivers from the same family or compatible third-party components that match the 2V-4V operating range and 6-MLP/DFN package constraints.
