Overview
The DRV8824PWP is a bipolar stepper motor controller IC manufactured by Texas Instruments. It integrates a power stage with a microstepping indexer and step/direction control interface. The device operates within a supply voltage range of 8.2 V to 45 V and supports an output current of 1.6 A. It features adjustable microstepping resolution from full step to 1/32 step. The component is housed in a 28-pin HTSSOP package and is designed for operation across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a microstepping indexer with step and direction control logic
- Supports adjustable microstepping resolution up to 1/32 step
- Includes built-in blank time adjustment for phase current regulation
Applications
- Bipolar stepper motor drive systems
- Motion control applications requiring precise positioning
- Industrial automation equipment
Procurement Notes
Verify the specific suffix PWP indicates the tube packaging variant distinct from the PWPR reel version. Confirm RoHS compliance status and check for any Product Change Notifications regarding manufacturing location or material updates. Ensure the ordering part number matches the required package type and lead frame finish specifications defined in the official datasheet.
Selection Notes
Select this component for applications requiring integrated microstepping control without external processors. The 1.6 A output capability suits moderate load requirements. Verify that the system voltage remains within the 8.2 V to 45 V operating window. Consider thermal management solutions due to the surface mount package constraints and power dissipation characteristics under load.
Part Context
This part belongs to the DRV8824 family of stepper motor drivers from Texas Instruments. It serves as a complete motion control solution combining logic and power stages. The device is designed to simplify system design by reducing the component count required for driving bipolar stepper motors in various industrial and commercial applications.
Replacement Considerations
The DRV8824PWPR is a compatible alternative offering identical electrical performance but supplied in tape-and-reel packaging instead of tubes.
