LTC3305 - Lead-Acid Battery Balancer

General Description

The LTC®3305 balances up to 4 lead-acid batteries connected in series.

It is intended to be used in conjunction with a separate pre-existing battery charger as part of a high performance battery system.

All voltage monitoring, gate drive, and fault detection circuitry is integrated.

Key Features

  • n Single IC Balances Up to Four 12V Lead-Acid Batteries in Series n All NFET Design n Stackable to Balance Larger Series Battery Packs n Standalone Balancing Operation: Requires No External μP or Additional Control Circuitry n Balancing Current Limited by External PTC Thermistor n Continuous Mode and Timer Mode n Programmable UV and OV Fault Thresholds n Programmable Termination Time and Termination Voltage n Thermally Enhanced 38-Lead TSSOP Package.
