Procurement Notes
Verify component obsolescence status before integration into new designs. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints for the 44-pin SSOP package. Review final datasheet specifications for thermal management requirements during operation.
Selection Notes
Select this component only for legacy system maintenance or specific low-voltage bipolar stepper applications. Evaluate alternative active components for new product development due to obsolete status. Consider power dissipation limits and thermal performance when designing heat sinks or PCB copper areas for sustained operation.
Part Context
This part belongs to onsemi's motor driver portfolio, specifically targeting bipolar stepper motors. It integrates H-bridge drivers with control logic to simplify system design. The 44-pin SSOP packaging allows for compact implementation in space-constrained electronic devices requiring precise rotational control.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements may require schematic redesign. Consult manufacturer archives for potential next-generation equivalents.
