Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the exact voltage and current requirements match the target application's specifications. Ensure compatibility with the intended motor's Hall sensor signal levels. Check for any regional compliance certifications required for the end product. Validate that the package type matches the PCB footprint design constraints.

Selection Notes

Choose this component for applications requiring a compact solution for three-phase BLDC motor control without external sensing components. It is suitable for designs prioritizing low component count and reduced board space. Consider its voltage range and current capacity against the motor's operational needs. Evaluate the need for integrated protections versus external circuitry based on system safety requirements.

Part Context

This part belongs to Rohm Semiconductor's family of motor driver ICs focused on fan control applications. It represents a consolidated solution combining control logic and power stages. Similar parts in the lineup may offer different voltage ranges or current capabilities. The integration level reduces the bill of materials compared to discrete solutions.

Replacement Considerations

Direct substitutes must match the pinout, voltage range, and current handling capabilities. Verify functional equivalence in terms of Hall sensor interface and protection features. Consult official replacement lists from Rohm for confirmed cross-references. Ensure mechanical compatibility if physical dimensions are critical.
