Procurement Notes
Verify component authenticity through official onsemi channels or authorized distributors. Confirm RoHS compliance status and moisture sensitivity level prior to handling. Check for product discontinuation notices as availability may be limited. Ensure storage conditions meet humidity requirements to prevent damage before soldering.
Selection Notes
Select this driver for applications requiring low standby current and compact surface-mount packaging. Consider the 800 mW power dissipation limit when designing thermal management solutions. Verify that the required motor voltage falls within the 5.5 V to 16 V operational window. Evaluate the SSOP-J-20 footprint compatibility with existing PCB layouts.
Part Context
This part belongs to the LB11852FV series of fan motor drivers from onsemi. It shares design characteristics with related models like the LB11850VA-TLM-H but differs in package type and specific electrical parameters. The series targets efficient motor control solutions within the broader portfolio of intelligent power and sensing technologies offered by the manufacturer.
Replacement Considerations
