LB11923V-A-TLM-E

Overview

The LB11923V-TLM-E is a bipolar PWM motor driver manufactured by onsemi, designed for brushless DC (BLDC) fan applications. It operates within a supply voltage range of 4.4V to 7V and features a 44-LSSOP surface-mount package. The device integrates three half-bridge pre-drivers and supports PWM interface control for commutation and direction management. It functions reliably across an operating temperature range of -20°C to 80°C and complies with RoHS3 standards.

Feature Summary

Integrates three half-bridge pre-drivers for efficient BLDC motor control
Supports PWM interface for precise commutation and direction management
Designed for low-voltage operation suitable for fan motor applications

Applications

Brushless DC (BLDC) fan motors
Computer cooling systems
Server chassis ventilation

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Procurement should focus on verifying stock availability through authorized distributors or exploring qualified replacement options. Ensure that any sourced units are genuine and match the specified 44-LSSOP package dimensions and pinout configuration.

Selection Notes

Select this driver for low-voltage BLDC applications requiring integrated pre-driver functionality. Verify compatibility with the target system's 4.4V to 7V power rail. Consider the 44-pin LSSOP footprint for PCB layout constraints. Confirm thermal requirements align with the -20°C to 80°C ambient operating range specified for this device.

Part Context

Part of the LB11923 series from onsemi, focusing on fan motor control solutions. This specific variant utilizes a 44-lead SSOP package. It belongs to the broader PMIC category under motor drivers and controllers, specifically tailored for bipolar PWM applications in consumer electronics and computing hardware.

Replacement Considerations

Consult official onsemi documentation for confirmed substitute part numbers due to the EOL status. Cross-reference electrical parameters such as supply voltage range and output configuration when evaluating alternatives.
