- Industrial automation equipment
Procurement Notes
Verify the specific suffix E2 against the manufacturer's official documentation to ensure compliance with RoHS directives and environmental standards. Confirm that the HTSSOP-B-24 package dimensions match your PCB footprint requirements. Check humidity sensitivity levels if storage or reflow conditions exceed standard limits. Ensure the 19 V to 28 V supply range aligns with your system's power delivery capabilities before finalizing procurement.
Selection Notes
Select this component when driving bipolar stepper motors requiring up to 1.2 A at voltages between 19 V and 28 V. Consider the 24-pin HTSSOP-B package for surface-mount integration. Evaluate the thermal performance given the 4 W power dissipation limit and the 150 °C junction temperature maximum. Compare against other drivers in the BD63940 series if different current ratings or package types are needed for your specific motion control design.
Part Context
This part belongs to the BD63940 series of motor drivers from ROHM Semiconductor. It is categorized under PMIC - Power Management ICs, specifically within the Motor / Motion / Ignition Controllers & Drivers subcategory. The series includes variants like the BD63920MUV-E2, which offers different current and voltage specifications. The BD63940EFV-E2 is designed for robust bipolar stepper motor applications.
Replacement Considerations
