Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution channels may not stock new units, and availability is limited to existing inventory or secondary markets. Verify the authenticity of any available sources and confirm RoHS compliance status through official documentation before procurement planning.

Selection Notes

Engineers should evaluate alternative components due to the discontinued status of this part. Consider drivers with similar voltage ranges and HSSOP-14 packaging if space constraints are critical. Ensure that replacement options support the required Hall sensor interface and open-loop control logic for seamless integration into existing designs.

Part Context

Part of the LB11961 series, this IC integrates driver circuitry for single-phase motors. It simplifies design by combining control logic and power output stages. The HSSOP-14 package allows for compact board layouts. It targets cost-sensitive applications where precise closed-loop feedback is not mandatory.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the EOL status, direct pin-to-pin replacements are not explicitly identified in the source material.
