LTC3300ILXE-2#PBF

Battery Management Overview

The LTC3300ILXE-2#PBF is a battery management IC designed for addressable, high-efficiency, bidirectional multicell battery balancing. It supports Lithium-ion and Lithium Iron Phosphate (LiFePO4) chemistries within a 36 V operating supply voltage range. The device provides a regulated 4.8 V output capable of delivering 55 mA. Packaged in an LQFP-48 surface-mount format, it operates between -40°C and +125°C and holds AEC-Q100 qualification.

Battery Management Feature Summary

• Bidirectional energy transfer enables both cell balancing and power delivery functions.
• Addressable architecture allows integration into multi-device systems with individual control.
• High efficiency design optimizes energy usage during charge and discharge cycles.

Battery Management Applications

• Multicell lithium-ion battery pack management
• Lithium Iron Phosphate (LiFePO4) battery protection systems
• Automotive battery modules requiring AEC-Q100 compliance

Battery Management Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and functional compatibility. The #PBF designation indicates lead-free packaging. Confirm availability status as distribution channels may report limited stock or restricted sales regions. Ensure the ordering part number matches the exact electrical specifications required for the target application circuit.

Battery Management Selection Notes

Select this component for applications requiring integrated bidirectional balancing rather than passive dissipation. Verify that the system input voltage remains within the 36 V limit. Consider the LQFP-48 thermal performance for the intended enclosure. Ensure the controller interface supports the addressable communication protocol defined in the datasheet for proper multicell synchronization.

Battery Management Part Context

This part belongs to the LTC3300 series from Analog Devices, specialized for advanced battery management. It differs from standard balancers by supporting bidirectional current flow, allowing energy redistribution among cells rather than simple bleeding. The ILXE-2 variant specifies the industrial temperature grade and package type.

Battery Management Replacement Considerations

Check for direct substitutes within the LTC3300 family, such as the LTC3300HUK-1#PBF, noting differences in package style and specific feature sets. Cross-reference official Analog Devices substitution guides to ensure functional equivalence without redesigning the PCB layout.
