LB11868V-TLM-H

Overview

The LB11868V-TLM-H is a fan motor driver manufactured by onsemi, designed for brushless DC (BLDC) applications. It operates within a supply voltage range of 4 V to 16 V and draws a typical quiescent current of 10.5 mA. The device features two half-bridge outputs and utilizes an SSOP-J-20 surface-mount package. It supports PWM speed control interfaces and functions effectively across an operating temperature range from -30°C to +95°C. The component has a maximum power dissipation rating of 800 mW and is classified under humidity-sensitive devices.

Feature Summary

• Integrated dual half-bridge output configuration for driving fan motors
• Supports PWM-based speed control interface for precise regulation
• Designed specifically for brushless DC (BLDC) fan applications

Applications

• Fan controller systems
• Brushless DC motor drive circuits
• HVAC cooling unit drivers

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Distribution channels indicate restricted availability or discontinuation status. Verify current stock levels and obsolescence notices through authorized distributors before design finalization. Ensure compliance with RoHS requirements via official material composition documents.

Selection Notes

Select this part only if BLDC fan driver functionality with a 4 V to 16 V input range is required. The SSOP-J-20 package must be compatible with the target PCB footprint. Consider the -30°C to +95°C operating temperature range against environmental conditions. Due to EOL status, evaluate alternative components for new designs.

Part Context

The LB11868V belongs to the LB11868V series of motor controllers and drivers produced by onsemi. It falls under the broader category of PMIC - Power Management ICs, specifically within Fan / Motor Controllers / Drivers. The TLM-H suffix denotes the specific tape-and-reel packaging variant in the SSOP-J-20 form factor.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Given the End-of-Life status, consult onsemi technical support or authorized distributors for recommended functional replacements.
