LTC3300ILXE-1#PBF

Battery Management Overview

The LTC3300ILXE-1#PBF is a high-efficiency bidirectional multicell battery balancer from Analog Devices, designed for stacks up to six cells. It operates with a maximum supply voltage of 36V and supports Lithium-ion and LiFePO4 chemistries. The device integrates transformer-based active balancing with fault protection and serial interface control. It is housed in a 48-pin LQFP package (7x7 mm) and functions within an operating temperature range of -40°C to +125°C.

Battery Management Feature Summary

• Transformer-based bidirectional active balancing for efficient energy transfer between adjacent cells
• Integrated fault protection circuitry including overvoltage, undervoltage, and thermal shutdown detection
• Serial interface for addressable configuration and monitoring of individual cell voltages

Battery Management Applications

• Lithium-ion battery pack management systems
• LiFePO4 battery stack balancing applications
• High-reliability energy storage systems requiring cell equalization

Battery Management Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence per Analog Devices standards. Confirm the LQFP-48 package dimensions match your PCB footprint requirements. Ensure the design supports the 36V maximum input voltage constraint. Check current availability status as distribution may be limited or subject to factory order constraints.

Battery Management Selection Notes

Select this component when active balancing is required for multi-cell stacks up to six cells. It is suitable for applications demanding high efficiency and integrated fault protection. Consider the LQFP-48 package size for board space constraints. Verify compatibility with the system's serial communication protocol for addressing and control.

Battery Management Part Context

This part belongs to the LTC3300 family of battery management ICs. It is specifically the ILXE-1 variant, indicating industrial temperature rating and the standard LQFP package. It complements other PMIC solutions by providing specialized active balancing capabilities rather than simple passive dissipation.

Battery Management Replacement Considerations

Direct substitutes include the LTC3300HLXE-1#PBF for higher reliability grades or the LTC3300ILXE-2#WPBF for automotive qualification. Verify pinout and software compatibility before substitution.
