Procurement Notes
Verify the exact suffix 'PWPR' against the manufacturer's official datasheet to confirm the HTSSOP/SOIC package type and reel quantity specifications. Ensure the component meets RoHS compliance requirements for your specific region. Cross-reference the ordering number with the latest Texas Instruments documentation to avoid discrepancies in pinout or thermal characteristics.
Selection Notes
Select this component when driving unipolar stepper motors requiring up to 1.5 A per phase. It is suitable for applications needing a wide input voltage range up to 60 V. Consider the 20-pin SOIC package for surface-mount assembly. Verify that the thermal performance of the chosen package meets the system's heat dissipation requirements under maximum load conditions.
Part Context
This part belongs to the DRV880x series of motor drivers from Texas Instruments. The series includes variants like the DRV8803 and DRV8805, differentiated primarily by output current capabilities and package options. These devices are designed for robust motor control in industrial and consumer applications.
Replacement Considerations
The DRV8803PWPR serves as a related variant within the same family, offering different current ratings. Verify compatibility regarding pinout and electrical specifications before substitution. Consult the official datasheet for detailed comparison of thermal and electrical parameters.
