Overview
The LB1989-MPB-E is a three-phase stepper motor driver manufactured by onsemi. It is housed in a 28-HSOP surface-mount package with dimensions of 0.220 inches (5.60 mm) width and includes two heat tabs for thermal management. This component is designed to drive three-phase synchronous or hybrid stepper motors, providing integrated control logic and power stages. The device supports various operating modes to optimize performance and efficiency for motion control applications.
Feature Summary
- Integrated three-phase power stage for direct stepper motor driving
- Surface-mount package design with integrated heat dissipation tabs
- Built-in control logic for simplified interface requirements
Applications
- Three-phase stepper motor systems
- Industrial automation equipment
- Precision motion control devices
Procurement Notes
Verify the current product status as sources indicate this part may be obsolete. Confirm availability through authorized distributors or check for recommended replacement components if active supply is required. Ensure the 28-HSOP package footprint matches the target PCB layout before procurement.
Selection Notes
Select this component for designs requiring a dedicated three-phase stepper driver in a compact surface-mount form factor. Consider the thermal performance provided by the heat tabs when designing the PCB copper area. Verify compatibility with the specific voltage and current requirements of the intended three-phase motor load.
Part Context
This part belongs to onsemi's portfolio of motor drivers and controllers. It falls under the broader category of power management and signal control solutions used in industrial and consumer electronics. The HSOP package variant is typical for space-constrained applications requiring robust thermal handling capabilities.
Replacement Considerations
Sources explicitly list the LB1989-MPB-E as Obsolete. Designers should consult official onsemi documentation for qualified replacement parts or updated series within the EcoSpin or similar motor driver families that offer equivalent three-phase driving capabilities.
