Procurement Notes
Verify the exact suffix E-2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the 10-VSON exposed pad is properly soldered for thermal dissipation. Confirm that the 1.8 V minimum supply voltage aligns with the system's power rail capabilities during operation.
Selection Notes
Select this component when a highly integrated, low-voltage solution for notebook fan control is required. It is suitable for designs prioritizing small footprint and low standby current. Consider the 700 mA output limit and ensure it meets the specific torque and speed requirements of the target fan motor application.
Part Context
This part belongs to ROHM's series of highly integrated motor drivers aimed at portable computing devices. It simplifies design by combining logic and drive circuits. The family focuses on reducing board space and component count for consumer electronics requiring efficient thermal regulation.
Replacement Considerations
The BD67173NUX-E2 is a related model within the same product line. Verify functional equivalence regarding voltage ranges and output currents before substitution. Cross-reference pinouts and thermal characteristics to ensure compatibility with existing PCB layouts.
