LB11867FVL-TLM-E

Overview

The LB11867FVL-TLM-E is a single-phase motor and fan controller IC manufactured by onsemi. It functions as a pre-driver for variable-speed single-phase full-wave fan motors. The device is housed in an SSOP-16 surface-mount package with dimensions of 5.2 x 4.4 x 1.3 mm. It operates within a supply voltage range of 4 V to 15 V, supporting a maximum collector current of 1.5 A. The component features a typical switching frequency of 23 kHz and has a rated converter power of 0.8 W. It is designed for operation across a temperature range of -30 °C to +95 °C.

Feature Summary

• Integrated pre-driver architecture optimized for variable-speed single-phase full-wave fan motor control applications
• Surface-mount SSOP-16 packaging facilitates automated assembly and compact board layout integration
• Operational stability maintained across extended industrial temperature ranges suitable for server and computing environments

Applications

• Variable-speed fan control in computer peripheral devices
• Thermal management systems in industrial equipment
• Cooling solutions for server infrastructure
• Motor control in vending machines

Procurement Notes

Verify the specific suffix variant against official datasheets, as ordering codes may denote package or tape-and-reel specifications that do not alter functional performance. Confirm availability status through authorized distribution channels, as lifecycle changes may affect production continuity. Ensure environmental compliance documentation matches project requirements prior to final procurement authorization.

Selection Notes

Select this component when designing control circuits for single-phase AC fan motors requiring variable speed regulation. The integrated pre-driver topology reduces external component count compared to discrete solutions. Verify that the 1.5 A current rating and 15 V maximum supply voltage align with the target motor's electrical characteristics and thermal dissipation capabilities within the intended enclosure constraints.

Part Context

This part belongs to onsemi’s portfolio of motor and motion controllers, specifically targeting fan and small motor driver applications. It complements other series components like the LB11660 and LB11867 families, offering specialized functionality for single-phase full-wave configurations. The device supports the company's focus on efficient thermal management solutions for computing and industrial hardware sectors.

Replacement Considerations

Direct substitutes include the LB11867FV-TLM-H variant within the same product family. Cross-reference pinouts and electrical parameters with equivalent offerings from other manufacturers only if confirmed compatible through official cross-reference data sheets.
