Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Confirm package integrity and moisture sensitivity handling requirements prior to assembly. Cross-reference pinouts with official datasheets to ensure compatibility with existing PCB layouts. Validate thermal performance under maximum load conditions.

Selection Notes

Select this component for designs requiring a compact, integrated BLDC driver solution. Ensure input voltage aligns with the 5V-22V operating range. Consider the 1.3A output capability against motor load requirements. Verify that the 28HSOP package fits the available board space and thermal management strategy.

Part Context

This part belongs to onsemi's motor driver portfolio, categorized under PMIC and Motor Drivers. It serves as a specialized solution for fan control, distinct from general-purpose motor controllers. The series focuses on integrated functionality to reduce external component count in cooling applications.

Replacement Considerations
