LB11867FV-MPB-H

Overview

The LB11867FV-MPB-H is a single-phase brushless DC motor controller manufactured by onsemi. It functions as a pre-driver for variable-speed full-wave fan motors, designed for integration into computing peripherals, industrial systems, servers, and vending machines. The component operates within a supply voltage range of 6 V to 50 V and supports an output current of 1 A. It features a low operating supply current ranging from 6 mA to 50 mA and dissipates up to 800 mW of power. The device is housed in a compact MFP-14S surface-mount package and is rated for operation between -30°C and +80°C.

Feature Summary

• Integrated pre-driver architecture for variable-speed full-wave fan motors
• Surface-mount design utilizing the MFP-14S package for space-constrained applications
• Operational capability across a wide temperature range suitable for industrial environments

Applications

• Computing and peripheral equipment cooling systems
• Industrial machinery ventilation control
• Server rack thermal management units
• Vending machine internal climate regulation

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Confirm availability status as distribution channels may list this component as obsolete or end-of-life. Ensure that any substitute components maintain identical package dimensions and thermal characteristics to fit existing board layouts without modification.

Selection Notes

Select this component when designing single-phase brushless fan motor circuits requiring integrated pre-driver functionality. Consider the MFP-14S package constraints for PCB layout planning. Evaluate the 1 A output current capacity against the specific motor coil requirements. Verify that the operating temperature range aligns with the environmental conditions of the target application system.
