Overview
The LB11850VA-TLM-E is a single-phase bipolar fan motor driver featuring integrated speed control functionality. It operates as a pre-driver with a half-bridge output configuration, designed to interface with PWM signals for precise motor regulation. The device supports dual supply voltage ranges: 4.5V to 5.5V and 5.5V to 16V, accommodating various system power architectures. With a power dissipation rating of 900 mW, it provides efficient thermal management for compact designs. This component is classified under Motor/Motion/Ignition Controllers & Drivers and utilizes a PDSO24 package.
Feature Summary
- Integrated speed control function compatible with speed feedback signals
- Single-phase bipolar fan motor driver architecture
- PWM interface for digital speed regulation
Applications
- Fan controller systems
- Brushed DC motor control applications
- Single-phase full-wave pre-driver circuits
Procurement Notes
Verify the current lifecycle status before procurement, as this part may be obsolete or subject to discontinuation by the manufacturer. Confirm that the PDSO24 package and specific voltage ranges align with your design requirements. Ensure compliance with moisture sensitivity levels during storage and handling. Cross-reference the exact suffix TLM-E to guarantee correct pinout and electrical characteristics.
Selection Notes
Select this component for applications requiring a dedicated single-phase bipolar fan driver with built-in speed control. It is suitable for designs needing a 900 mW power dissipation capability and operation within 4.5V to 16V supply ranges. Consider the PDSO24 package size for PCB layout constraints. Verify compatibility with PWM input signals and required feedback mechanisms for closed-loop speed regulation.
Part Context
This component belongs to onsemi's standard product portfolio, specifically within the Motor Drivers and Controllers category. It is engineered for reliable performance in fan control and brushed DC motor applications. The device leverages established bipolar technology to deliver robust pre-driver functionality. Its classification highlights its role in motion control solutions rather than general-purpose logic or power switching.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Check for direct replacements from the same series or consult manufacturer obsolescence notices for recommended upgrades.
