LB11822-E

Overview

The LB11822-E is a three-phase brushless DC motor driver designed for fully integrated control and power stage functions. It operates within a supply voltage range of 9.5V to 28V, with an output current capability of 3.1A and maximum power dissipation of 3W. The device utilizes Pulse Width Modulation (PWM) for efficient motor control. It is housed in a 28-pin PDIP-H Fan-Fold package, which is RoHS compliant and lead-free. This component is specifically optimized for driving drum and paper feed motors in laser printers and plain paper copiers.

Feature Summary

• Fully integrated driver combining control logic and power stage for three-phase brushless DC motors
• Supports PWM operation for precise motor speed and torque regulation
• Designed for high-current applications with 3.1A output capability
• RoHS compliant and lead-free construction for environmental safety

Applications

• Driving drum motors in laser printers
• Controlling paper feed motors in laser printers
• Powering drum mechanisms in plain paper copiers
• Paper feed systems in plain paper copiers

Procurement Notes

Verify the specific suffix 'E' indicates the correct packaging and compliance status. Confirm the package type matches the required 28-pin DIP configuration. Check for obsolete status as some sources indicate this part may be discontinued. Ensure compatibility with existing PCB footprints for PDIP-H Fan-Fold packages. Validate that the 9.5V-28V operating range meets system requirements.

Selection Notes

Select this component when a fully integrated solution for three-phase BLDC motors is required. It is suitable for applications needing up to 3.1A output current. Consider the 28-pin DIP package for through-hole mounting needs. Verify thermal management capabilities given the 3W power dissipation rating. Ensure the application does not require AC or generic DC motor support beyond the specified BLDC function.

Part Context

The LB11822 belongs to the PMIC Motor Drivers, Controllers family from onsemi. It is a specialized IC for motion control in office equipment. The '-E' suffix typically denotes specific packaging or compliance variations. Related parts in this category include other three-phase drivers but may differ in current ratings or package types. This part is distinct from stepper motor controllers.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult onsemi directly for current alternatives if this part is obsolete. Cross-reference with other three-phase BLDC drivers from onsemi for functional equivalents. Verify pinout compatibility before considering any potential substitutes.
