LTC3305 - Lead Acid Battery Balancer

 

Description

The LTCÂŽ3305 balances up to 4 lead acid batteries connected in series. All voltage monitoring, gate drive, and fault detection circuitry is integrated. The LTC3305 is designed for stand-alone operation and does not require any external control circuitry.
The LTC3305 employs an auxiliary battery or an alternative storage cell to transfer charge to or from each individual battery in the stack. A mode pin provides two operating modes, timer mode and continuous mode. In timer mode, once the balancing operation is completed, the LTC3305 goes into a low power state for a programmed time and then periodically rebalances the batteries. In continuous mode, the balancing operation continues even after the batteries are balanced to their programmed termination voltage.
The LTC3305 is available in a thermally enhanced 38-lead TSSOP package.

Applications

  • Telecom Backup Systems
  • Home Battery Powered Backup Systems
  • Industrial Electric Vehicles
  • Energy Storage Systems (ESS)
  • Medical Equipment
