LB11867FV-W-AH

Overview

The LB11867FV-W-AH is a single-phase full-wave pre-driver designed for variable speed fan motor applications. It operates at frequencies up to 30 kHz and supports an output voltage of 18 V. The device features two outputs and has a power dissipation rating of 800 mW. It is housed in an SSOP package and is rated for operating temperatures up to 95°C.

Feature Summary

• Single-phase full-wave pre-driver architecture
• Variable speed control capability
• Dual output configuration

Applications

• Variable speed fan motor control
• Single-phase AC motor driving
• Full-wave rectification driver circuits

Procurement Notes

Verify the specific suffix 'AH' against the manufacturer's current datasheet to confirm pinout, temperature range, and compliance status. Ensure the SSOP package type matches the target PCB footprint. Confirm that the 18 V output voltage and 800 mW power dissipation limits are sufficient for the intended load conditions before finalizing procurement.

Selection Notes

Select this component when a dedicated single-phase full-wave pre-driver is required for fan motors. Consider the 30 kHz operating frequency limit and 18 V output capability. The SSOP package and 95°C thermal rating must align with the system's physical and environmental constraints compared to alternative packages or higher-rated devices.

Part Context

This part belongs to onsemi's motor driver family, specifically targeting single-phase applications. It serves as a pre-driver stage, distinct from complete bridge drivers, focusing on signal conditioning and drive capability for fan motors. The 'LB' prefix typically denotes logic-based motor control solutions within the manufacturer's portfolio.

Replacement Considerations

The LB11867RV-W-AH is a related variant within the same product line. Verify if the 'RV' suffix indicates a necessary change in package, temperature grade, or electrical characteristics before substituting.
