Key Features
- Addressable daisy-chain interface enables scalable multicell battery balancing across large Li-ion or LiFePO4 battery stacks with adjustable thresholds
- Bidirectional high-efficiency active cell balancing transfers energy between cells rather than dissipating it as heat, maximizing pack capacity utilization
- 48-pin QFN package integrates the complete balancing controller for compact BMS designs in EV and energy storage systems
Applications
The LTC3300IUK-2#PBF is used in battery management systems for electric vehicles, grid energy storage, and large-format portable power packs requiring active cell balancing to extend cycle life and maximize usable capacity. Its bidirectional energy transfer balancing transfers charge between adjacent cells with high efficiency, reducing pack imbalance that degrades capacity in multi-cell Li-ion stacks. The addressable daisy-chain interface enables stacking multiple LTC3300 ICs to manage battery packs with tens to hundreds of cells without additional isolation circuitry.

Frequently Asked Questions
How does the bidirectional balancing architecture of LTC3300IUK-2#PBF improve battery pack capacity versus passive balancing?
Unlike passive balancing that dissipates excess charge as heat through resistors, the LTC3300IUK-2#PBF performs active bidirectional energy transfer between cells with high conversion efficiency, typically above 90%. This recovers energy from stronger cells into weaker ones, increasing the usable capacity of a 6-cell to 12-cell Li-ion pack by up to 20% compared to resistive dissipation methods.
What cell chemistry and stack voltage ranges are compatible with the LTC3300IUK-2#PBF battery balancer?
The LTC3300IUK-2#PBF is designed for Li-ion and LiFePO4 cell chemistries with per-cell voltages typically from 2.5 V to 4.5 V. Using the daisy-chain addressable interface, multiple LTC3300IUK-2 devices can be stacked to balance battery packs with total stack voltages exceeding 100 V, covering both 48 V automotive mild-hybrid packs and higher-voltage EV traction battery systems.
For a 12-cell EV battery pack, how does daisy-chaining multiple LTC3300IUK-2#PBF ICs simplify the BMS design?
A 12-cell pack can be managed by 2 LTC3300IUK-2#PBF ICs each handling 6 cells, connected via the serial daisy-chain bus. This addressable interface requires only a 2-wire or 3-wire SPI-compatible link to the master BMS processor rather than 12 isolated measurement lines, eliminating the need for opto-isolators or isolated DC-DC converters for every cell level and significantly reducing BOM cost and PCB complexity.
