Overview
The DRV8424RGER is a bipolar stepper motor driver manufactured by Texas Instruments, designed for applications requiring precise motion control. It features an integrated half-bridge power stage capable of delivering up to 2.5 A of output current per phase. The device operates within a supply voltage range of 4.5 V to 33 V and supports step/dir control interfaces. It includes built-in protections such as overcurrent protection and thermal shutdown. The component is housed in a surface-mount package suitable for automated assembly and functions reliably across an operating temperature range from -40°C to +125°C.
Feature Summary
- Integrated half-bridge power stage with high-current capability
- Supports step and direction control interface for simplified integration
- Includes comprehensive protection mechanisms against overcurrent and thermal events
Applications
- Bipolar stepper motor control systems
- Industrial automation equipment
- Motion control modules
Procurement Notes
Verify the specific suffix RGER to confirm the reel packaging configuration and ensure compatibility with surface-mount assembly processes. Confirm that the 33 V maximum supply voltage aligns with your system design requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing location. Ensure proper thermal management strategies are implemented given the operational temperature limits.
Selection Notes
Select this component when driving bipolar stepper motors requiring up to 2.5 A per phase. It is suitable for designs needing a compact solution with integrated protection features. Consider the HTSSOP or similar surface-mount package availability for PCB layout constraints. Evaluate the 4.5 V minimum supply voltage requirement against your available power rails.
Part Context
This part belongs to the DRV8424 series of stepper motor drivers from Texas Instruments. The series offers various packages and configurations to suit different application needs. The DRV8424RGER specifically denotes the version packaged in reels for high-volume surface-mount production. It shares core functional characteristics with other variants in the family while differing in packaging and handling specifications.
Replacement Considerations
Consult official documentation for direct pin-to-pin replacements within the DRV8424 family. Verify electrical parameters and package dimensions before substituting with other stepper driver ICs.
