Overview
The A4952ELYTR-T is a fully integrated DC motor driver IC from Allegro MicroSystems, designed for brushed DC motor control. It features a half-bridge output configuration with two channels and utilizes DMOS technology. The device operates within a supply voltage range of 8V to 40V and supports an output current of 2A. It is housed in a 10-MSOP package with an exposed pad (10-MSOP-EP) for enhanced thermal performance. The component functions as both the controller and power stage, supporting parallel interfaces.
Feature Summary
- Fully integrated design combining control logic and power stages
- Supports PWM operation with internal synchronous rectification
- Includes comprehensive protection mechanisms such as overcurrent and thermal shutdown
Applications
- Brushed DC motor speed and direction control
- General purpose motor drive systems
- Industrial automation equipment
Procurement Notes
Verify the specific suffix ELYTR-T against official Allegro MicroSystems documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target PCB footprint, specifically the 10-MSOP-EP package dimensions. Confirm that the 2A output rating meets the application requirements before finalizing procurement decisions.
Selection Notes
Select this component when a compact, fully integrated solution for brushed DC motors is required. It is suitable for applications needing a half-bridge configuration with moderate current handling capabilities. Consider the exposed pad package for thermal management needs. Compare against the A4953ELJTR-T if higher current capacity is necessary, or the A4950ELJTR-T for different interface requirements.
Part Context
This part belongs to the A495x family of DC motor drivers from Allegro MicroSystems. It shares architectural similarities with other members like the A4953 and A4954, differing primarily in output current ratings and specific packaging options. The family is designed to simplify motor control designs by integrating necessary protection and control features into a single chip.
Replacement Considerations
The A4953ELJTR-T serves as a related alternative within the same product family, offering similar integration but with a 2A output rating. Verify pin-to-pin compatibility and thermal requirements when considering substitutes. No direct public substitute part numbers are confirmed for exact replacement without engineering review.
