Battery Management Procurement Notes

Verify the suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm the specific variant matches the required lead-acid cell count and input voltage specifications for the target application. Ensure compatibility with the intended thermal management solution given the QFN EP package type.

Battery Management Selection Notes

Select this component for designs requiring integrated PowerPath management alongside high-current lead-acid charging. It is suitable for applications utilizing solar inputs where MPPT is necessary. Consider the 3.2A current limit and 35V maximum input voltage when sizing external components and input sources.

Battery Management Part Context

This part belongs to the LTC4162 family of battery management ICs from Analog Devices. The family includes variants supporting different battery types such as Lithium-ion and LiFePO4. The SADM suffix specifically denotes the configuration for lead-acid battery applications within this series.

Battery Management Replacement Considerations

LTC4162EUFD-SADM#PBF offers the same functional characteristics in tube packaging instead of tape-and-reel.
