Procurement Notes

Verify component status carefully as this part is classified as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors only. Ensure design-in decisions account for potential supply discontinuation and plan for long-term maintenance strategies accordingly.

Selection Notes

Select this component specifically for applications requiring dedicated hardware-level protection for two-cell lithium-ion setups. Evaluate thermal performance within the specified operating range. Consider alternative active parts if long-term production stability is required due to the obsolete status.

Part Context

This component belongs to onsemi's battery management portfolio, focusing on safety and protection functions rather than active charging control. It complements other power management ICs by providing critical fault isolation for cell integrity.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineering teams should initiate a formal replacement qualification process using current onsemi product lines.
