LB11852FV-MPB-E

Overview

The LB11852FV-MPB-E is a fan motor driver manufactured by onsemi, designed for precise control of small DC motors. It operates within a supply voltage range of 5.5 V to 16 V and draws a typical operating supply current of 15 mA. The device supports surface mount installation in an SSOP-J-20 package and functions reliably across an extended temperature range from -30°C to +95°C. With a power dissipation rating of 800 mW, it integrates necessary drive circuitry for efficient thermal management in compact electronic assemblies.

Feature Summary

• Integrated driver architecture optimized for fan motor applications
• Extended operational temperature capability for harsh environments
• Compact surface-mount packaging for space-constrained designs

Applications

• Computer cooling fan systems
• Server chassis ventilation modules
• Consumer appliance motor control

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Validate package marking against official datasheet specifications to prevent counterfeit substitution. Ensure storage conditions respect moisture sensitivity levels prior to reflow soldering processes.

Selection Notes

Evaluate the 16 V maximum supply voltage limit against system power rails. Assess the 800 mW power dissipation capacity relative to expected thermal loads. Consider the SSOP-J-20 footprint compatibility with existing PCB layouts. Verify that the -30°C to +95°C operating range meets environmental demands.
