Procurement Notes
Verify the NRND status before procurement, as this component is not recommended for new designs. Confirm the specific suffix E2 matches project requirements. Ensure compatibility with the 40-pin HTSSOP-B package dimensions. Check humidity sensitivity handling procedures during storage and assembly. Validate that the 10V-28V operating range aligns with system power supplies.
Selection Notes
Select this driver for bipolar stepper motors requiring up to 2A continuous current. Consider the 40-pin HTSSOP-B package for thermal management needs. Evaluate the mixed decay functionality against precision requirements. Verify interface compatibility between CLK-IN and parallel modes. Assess thermal performance within the specified temperature range.
Part Context
This part belongs to the BD6387EFV series of high-performance stepping motor drivers. It shares pin compatibility with related models like BD6385EFV and BD6383EFV. The series emphasizes reliability and compact design with back-side heat dissipation capabilities. It represents a specialized solution for bipolar motor control within ROHM's PMIC portfolio.
Replacement Considerations
Consider BD6385EFV or BD6383EFV for pin-compatible alternatives within the same series. Verify functional equivalence regarding current ratings and interface options. Check datasheet updates for any changes in electrical characteristics or packaging specifications.
