LB11867FV-TLM-E

Overview

The LB11867FV-TLM-E is a variable speed single-phase full-wave pre-driver designed for fan motor control. It operates within a supply voltage range of 5.5 V to 16 V, delivering an output current of 20 mA through a single channel. The component utilizes an SSOP-16 surface-mount package with dimensions of 4.4 mm by 5.2 mm and a height of 1.3 mm. It supports operating temperatures from -30 °C to +95 °C.

Feature Summary

• Provides single-phase full-wave drive capability for variable speed fan motors
• Integrates protection mechanisms against overcurrent and thermal overload conditions
• Features a compact SSOP-16 surface-mount package suitable for space-constrained designs

Applications

• Computer peripheral cooling systems
• Industrial equipment ventilation
• Server rack airflow management
• Vending machine internal climate control

Procurement Notes

Verify the specific suffix (E vs H) as availability varies; the E variant may be obsolete. Confirm package integrity upon receipt. Ensure static-safe handling protocols are followed during installation. Validate electrical parameters against the official datasheet before integration into final assemblies.

Selection Notes

Select this component for applications requiring simple single-phase fan control without complex PWM requirements. It is suitable for systems where cost-effective thermal management is prioritized. Consider alternative drivers if higher current capacity or multi-phase synchronization is required.

Part Context

This part belongs to onsemi's motor driver portfolio, specifically targeting low-power fan applications. It serves as a pre-driver stage, simplifying the interface between microcontrollers and fan motors in consumer and industrial electronics.

Replacement Considerations

Check for direct substitutes such as the LB11867FV-TLM-H. Verify pin compatibility and electrical specifications before substitution. Note that some variants may be discontinued.
