Applications
The LTC3305IFE#PBF is designed for backup power systems and UPS equipment that use multi-cell 12 V or 24 V lead-acid battery strings, where cell imbalance reduces capacity over time. It is also used in industrial energy-storage racks and telecom battery plants where engineers need a reliable, low-maintenance balancing solution operating across a -40°C to 85°C temperature range.

Frequently Asked Questions
How many lead-acid cells can LTC3305IFE#PBF balance in a single stack?
The LTC3305IFE#PBF balances up to 4 lead-acid cells connected in series, with each cell typically operating around 2 V to 2.4 V, allowing the device to manage stack voltages up to approximately 12 V while equalizing charge levels across all cells.
What temperature range does LTC3305IFE#PBF support for industrial battery backup applications?
The LTC3305IFE#PBF is rated for an industrial temperature range of -40°C to 85°C, making it suitable for outdoor telecom enclosures, factory UPS cabinets, and other environments where temperatures fluctuate significantly across seasons.
What package does LTC3305IFE#PBF use, and how many pins does it have?
The LTC3305IFE#PBF is housed in a 38-pin TSSOP (Thin Shrink Small Outline Package) measuring approximately 12.5 mm × 4.4 mm, providing a compact footprint that simplifies PCB layout in space-constrained battery management modules.
Is the balancing threshold on LTC3305IFE#PBF fixed or adjustable?
The balancing threshold is adjustable via an external resistor network, allowing designers to fine-tune the activation voltage to match the specific charge-equalization requirements of different lead-acid chemistries and capacity ratings, such as 20 Ah versus 100 Ah cells.
