LB11988V-TLM-E

Overview

The LB11988V-TLM-E is a three-phase brushless DC motor driver IC designed for fan motor applications. It features a full-wave current linear drive architecture. The device operates within a supply voltage range of 5 V to 22 V and supports a maximum output current of 1.3 A. It is housed in a 24-pin SSOP package with dimensions of 9.75 mm length and 5.6 mm width. The component functions as a bipolar parallel controller suitable for driving DC fan motors.

Feature Summary

• Three-phase full-wave current linear drive capability
• Optimized for driving DC fan motors
• Bipolar parallel control interface

Applications

• DC fan motor control systems
• Three-phase brushless DC motor drivers
• Electronic cooling solutions

Procurement Notes

Verify the manufacturer origin, as this part number is associated with both Sanyo and onsemi/Rochester Electronics due to corporate acquisitions. Confirm the specific datasheet version matches the required electrical characteristics. Ensure the 24-SSOP package variant aligns with your PCB footprint requirements. Check for RoHS compliance status if environmental regulations apply to your assembly process.

Selection Notes

Select this component when a dedicated three-phase linear driver is required for low-to-medium power fan applications. The 1.3 A current rating suits small to medium-sized fans. Consider the 24-pin SSOP package constraints for board space. Verify that the 5 V to 22 V operating range matches your system's power supply rails before integration.
