• Two-cell battery system safety circuits

Procurement Notes

This component is officially listed as discontinued by the manufacturer. Verification of current availability requires direct inquiry with authorized distributors or suppliers, as standard inventory channels may not hold stock. Confirm end-of-life status and potential obsolescence risks before finalizing procurement plans.

Selection Notes

Select this part only if compatibility with existing two-cell lithium-ion architectures is required. Due to its discontinued status, alternative components with similar voltage ratings and protection features should be evaluated for long-term supply chain stability and design continuity.

Part Context

The LV51139 series belongs to onsemi's portfolio of battery management solutions. This specific variant focuses on protecting lithium-ion cells from electrical faults in compact surface-mount packages, serving applications where space constraints and basic cell protection are primary design drivers.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers must identify cross-compatible devices based on pinout, voltage ratings, and protection thresholds through independent technical comparison.
