DESCRIPTION
LTC3305EFE
Lead Acid Battery Balancer
Demonstration circuit 2043B is a lead-acid battery balancer
. The LTC3305 balances up to four
lead-acid batteries connected in series and incorporates all
voltage monitoring, gate drive and fault detection circuitry.
The LTC3305 employs an auxiliary battery or an alternative
storage means to transfer charge to or from each individual
battery within the stack. There are two operating modes,
TIMER mode and CONTINUOUS mode, selected by the
MODE pin. In TIMER mode, once the balancing operation
is complete, the LTC3305 goes to 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 LTC3305EFE is available in a 7mm
×
7mm 38-lead
TSSOP surface mount package with exposed pad.
