Overview
The LB11867FV-MPB-E is a variable speed single-phase full-wave pre-driver for fan motors manufactured by onsemi. It operates within a supply voltage range of 6 V to 50 V and supports an output current of 1 A. The device functions with a working supply current between 6 mA and 50 mA, dissipating up to 800 mW of power. It is designed for surface mount installation in an MFP-14S package and maintains operational reliability across temperatures from -30°C to +80°C.
Feature Summary
- Provides variable speed control for single-phase brushless fan motors
- Integrates full-wave pre-driver circuitry for motor commutation
- Supports surface mount technology for compact board integration
Applications
- Variable speed cooling fans
- Single-phase brushless DC motor systems
- Thermal management modules requiring pre-driver control
Procurement Notes
This component is classified as obsolete and no longer manufactured by onsemi. Verification of availability requires checking authorized distributors for remaining stock or approved substitute part numbers. Ensure compliance with RoHS directives and confirm the specific suffix designation matches the required package and material specifications before procurement.
Selection Notes
Select this component for applications requiring a dedicated pre-driver for single-phase fan motors. Verify that the system voltage remains within the 6 V to 50 V range and that thermal constraints allow for 800 mW dissipation in the MFP-14S package. Confirm compatibility with the required operating temperature range of -30°C to +80°C for the intended environment.
Part Context
The LB11867FV-MPB-E belongs to the LB11867 series of motor controllers and drivers from onsemi. This series focuses on power management ICs specifically tailored for fan and motor applications. The device serves as a specialized pre-driver stage, distinct from complete H-bridge drivers, offering targeted functionality for single-phase AC or brushless DC fan control architectures.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. The LB11867FV-TLM-E is also listed as obsolete. Engineers should consult onsemi technical support for current alternative recommendations or evaluate generic single-phase pre-driver solutions that match the electrical specifications.
