Procurement Notes
Verify the specific suffix and package variant against the official onsemi datasheet to ensure compatibility with your design requirements. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region and production batch.
Selection Notes
Select this component when designing three-phase BLDC motor controllers requiring integrated high-side and low-side driver capabilities. Ensure the external MOSFETs selected are compatible with the drive voltage and current levels provided by the LB1823-E outputs. Consider thermal management solutions if operating at high duty cycles or temperatures.
Part Context
The LB1823 series belongs to onsemi's portfolio of intelligent power and sensing technologies, specifically targeting motor control applications. This predriver simplifies the design of robust motor drive systems by handling the complex gate drive requirements, allowing engineers to focus on system-level control algorithms and mechanical integration.
Replacement Considerations
Check for updated part numbers within the same family or alternative predrivers from onsemi that offer enhanced features or improved availability. Verify pin-to-pin compatibility and electrical specifications before substituting with components from other manufacturers.
