LTC3305EFE#PBF Datasheet PDF - Linear Technology

●The LTC3305EFE#PBF is a lead-acid Battery Balancer 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. 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 balancer 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.
