LB11850VA-TLM-H

Overview

The LB11850VA-TLM-H is a brushless motor driver manufactured by onsemi, designed for fan motor applications. It operates within a supply voltage range of 5.5 V to 16 V and draws a working supply current of 15 mA. The device supports surface mount installation in an SSOP-24 package and functions reliably across temperatures from -30°C to +95°C. With a power dissipation rating of 900 mW, it is suitable for compact designs requiring humidity sensitivity management.

Feature Summary

Integrated control and drive functionality for brushless DC motors
Surface-mount packaging optimized for automated assembly processes
Operational capability across extended industrial temperature ranges

Applications

Fan motor control systems
Brushless DC motor drivers
Motion control circuits

Procurement Notes

This component is currently listed as obsolete with a discontinued lifecycle status. Availability is restricted, and distributors may not stock this item in all regions. Verify end-of-life status and last-time-buy dates through official channels before finalizing design-in decisions. Sourcing should focus on authorized partners or verified surplus suppliers to ensure authenticity and compliance with RoHS material standards.

Selection Notes

Engineers selecting this part must account for its discontinued status when planning long-term production runs. The SSOP-24 package requires specific footprint considerations during PCB layout. Designers should evaluate the 16 V maximum supply voltage limit against their system requirements. Thermal management strategies must address the 900 mW power dissipation constraint under worst-case operating conditions.

Part Context

The LB11850VA belongs to onsemi's series of motor controllers and drivers. This specific model variant utilizes the TLM-H suffix designation within the SSOP-24 form factor. It falls under the broader category of PMIC power management ICs dedicated to motion control applications. The component represents a specialized solution for integrating motor drive logic with power switching elements.
