- Applications utilizing Microwire bus communication interfaces
- General illumination setups compatible with SOP-18 packaging
Procurement Notes
Verify the current lifecycle status before procurement, as this component is marked as Not Recommended for New Designs (NRND). Confirm that existing designs are supported and that no alternative replacement parts are required for ongoing production. Ensure compatibility with the specified SOP-18 package and Microwire interface requirements for legacy system maintenance.
Selection Notes
Select this component only for maintaining or repairing existing designs that specifically require the BD9285F-GE2 specifications. Due to its NRND status, it is unsuitable for new product development. Engineers should evaluate if newer ROHM LED drivers with similar boost topologies and EEPROM integration can replace this part for future projects to ensure long-term supply availability.
Part Context
This part belongs to the ROHM LED lighting driver series, specifically utilizing a boost converter architecture. It is distinguished by its integrated Microwire interface and EEPROM, allowing for flexible configuration. The SOP-18 package facilitates surface-mount installation, while the 150kHz switching frequency balances efficiency and component size for standard LED lighting applications.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. As the component is Not Recommended for New Designs, engineers must consult official ROHM resources or distributors for potential obsolescence management strategies or direct cross-reference recommendations.
