Procurement Notes
Verify the specific suffix PWPR corresponds to the HTSSOP-28 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the operating voltage and current ratings align with your motor specifications before integration.
Selection Notes
Select this component for applications requiring integrated stepper motor control with moderate current demands up to 1.4 A. Consider the 28-pin HTSSOP package for surface mount assembly constraints. Evaluate thermal performance based on the expected load current and ambient temperature conditions within the -40°C to +85°C operating range.
Part Context
This part belongs to the DRV8811 series of stepper motor drivers from Texas Instruments. It is designed as a complete solution for driving bipolar stepper motors, combining microstepping capability with power MOSFETs in a single compact package. The series targets cost-sensitive applications requiring reliable motion control.
Replacement Considerations
Check datasheets for alternative parts within the DRV88xx family or other TI stepper drivers to verify pin compatibility and electrical parameter alignment. Ensure substitute components match the required package type and thermal characteristics.
