Procurement Notes
Verify the specific suffix E2 against the official datasheet to confirm pinout and electrical characteristics match your design requirements. Check the lifecycle status, as this part may be marked as Not Recommended for New Designs. Ensure the HTSSOP-B-28 package dimensions align with your PCB footprint and thermal management strategy before finalizing procurement.
Selection Notes
Select this component when a bipolar stepper driver with 1.0 A continuous output is required. It is suitable for designs needing operation between 19 V and 28 V. Consider the 28-pin HTSSOP-B package for space-constrained surface mount applications. Verify that the integrated protection features meet the safety standards of the target system.
Part Context
This IC belongs to the Rohm semiconductor motor driver family, specifically designed for bipolar stepper motors. It integrates high-side and low-side DMOS outputs into a single chip. The device simplifies driver circuit design by combining control logic with power stages. It is distinct from unipolar drivers and offers higher efficiency through its parallel DMOS structure.
Replacement Considerations
The BD63847EFV-E2 is listed as a pin-compatible alternative within the same product line. However, it supports a higher output current of 2.0 A and a maximum voltage of 36 V. Verify if the increased ratings are necessary or if they impact thermal performance in the existing application.
