Procurement Notes
Verify the exact suffix designation against official documentation, as the TLM-H variant is explicitly listed as obsolete. Confirm availability status through authorized channels, as distribution may be restricted or discontinued. Ensure compliance with RoHS requirements and moisture sensitivity levels specified in the manufacturer's datasheet before procurement.
Selection Notes
Select this component for applications requiring a dedicated fan motor driver with moderate voltage tolerance. Consider the SSOP-J-20 package constraints for PCB layout. Evaluate the 800 mW power dissipation limit against thermal design requirements. Verify compatibility with the 5.5 V to 16 V supply range and ensure the operating temperature range meets environmental specifications.
Part Context
This part belongs to the LB11852FV series from onsemi, categorized under PMIC - Power Management ICs. It serves as a specialized solution for driving fan motors within broader motion and ignition control systems. The series provides integrated control capabilities suitable for consumer and industrial electronics requiring efficient motor management.
Replacement Considerations
The LB11852FV-TLM-H variant is documented as obsolete. No direct public substitute part numbers are confirmed for the LB11852FV-TLM-E model. Designers should consult official obsolescence notices or contact the manufacturer for recommended alternative components.
