LB11988HR-MPB-E

Overview

The LB11988HR-MPB-E is a fully integrated three-phase fan motor driver IC designed for DC fan applications. It utilizes bipolar technology and features a parallel interface for control signals. The device operates within a supply voltage range of 5V to 22V, making it suitable for various low-voltage motor control scenarios. Packaged in a 28-HSOP format, this component integrates both the control logic and power stages required for efficient motor driving.

Feature Summary

• Three-phase full-wave current linear drive capability
• Fully integrated control and power stage design
• Bipolar technology implementation for robust performance

Applications

• DC fan motor driving
• Computer cooling systems
• Server ventilation units

Procurement Notes

Verify the specific suffix MPB-E against official onsemi documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the 28-HSOP configuration. Cross-reference part numbers with authorized distributors to avoid obsolete variants or incorrect pinouts.

Selection Notes

Select this component when a dedicated three-phase driver for small DC fans is required. It is appropriate for designs needing integrated power stages without external MOSFETs. Consider the 5V-22V operating range and parallel interface requirements during system architecture planning.

Part Context

This part belongs to onsemi's standard product line focused on signal conditioning and control. It falls under the Motor Drivers category, specifically targeting fan motor applications. The series offers solutions for industrial and consumer electronics requiring reliable motor control.

Replacement Considerations

Check for direct substitutes such as the LB11988HR-TLM-E, which shares similar functional characteristics but may differ in packaging. Verify pinout compatibility before substitution.
