Procurement Notes

Verify the specific suffix '-TR' confirms the tape-and-reel packaging format required for automated assembly processes. Ensure the ordering part number matches the exact pinout and electrical specifications documented in the official ROHM datasheet. Confirm RoHS compliance status and environmental restrictions relevant to the target market. Cross-reference the HRP7 package dimensions against PCB footprint requirements to ensure mechanical compatibility during procurement validation.

Selection Notes

Select this component when a single-channel H-bridge solution is required for brushed DC motors operating between 6V and 32V. It is suitable for applications demanding up to 1A continuous current with integrated protection features. Consider the HRP7 package size for space-constrained designs. Verify that the thermal performance under expected load conditions aligns with the system's heat dissipation capabilities before finalizing the selection.

Part Context

This part belongs to the BD623XHFP series of high-current H-bridge drivers from ROHM. It shares pin compatibility with other members of the family, facilitating design upgrades or replacements within existing hardware architectures. The series is characterized by robust output stages and extensive protection circuits tailored for reliable motor operation in various consumer and industrial environments.

Replacement Considerations

The BD62321HFP is a compatible alternative offering higher current capacity (3A) while maintaining pin compatibility. For lower current requirements, the BD6231F-E2 serves as a variant with similar electrical characteristics but may differ in packaging or reel specifications. Verify functional equivalence and thermal limits when substituting.
