Procurement Notes
This component is officially listed as End-of-Life (EOL) with discontinuation effective November 2015. Availability is limited to secondary market distributors such as Rochester Electronics. Verify authenticity and storage history carefully due to the obsolete status. Ensure compatibility with existing PCB footprints before procurement.
Selection Notes
Select this part for legacy designs requiring integrated three-phase BLDC drive with high thermal tolerance. The 1.2A output current suits moderate load applications. The 24-SSOP-J package requires specific surface mount layout considerations. Evaluate alternative active components if new production volume is required, as this part is discontinued.
Part Context
The LB11685 series represents onsemi's dedicated motor driver solutions for white goods and industrial applications. This specific model combines bipolar technology with integrated power switching. It simplifies design by merging gate drive and protection functions into a single compact package suitable for space-constrained motor control systems.
Replacement Considerations
No direct public substitute part numbers are documented in the provided source material. Designers should consult official obsolescence notices or contact onsemi sales for recommended cross-reference alternatives for new designs.
