DEMO MANUAL DC2064A
LTC3300-1/LTC6803-2
Bidirectional Cell Balancer
Description
Demonstration Circuit DC2064A is a bidirectional cell
balancer using two
LTC
®
3300-1
ICs to achieve active cell
balancing of up to 12 Li-Ion batteries. The board uses the
LTC6803-2
multi-cell addressable battery stack monitor to
measure cell voltages and two LTC3300-1 ICs to provide
active cell balancing. The demonstration circuit uses a two
window GUI developed for the DC2064A. One window is
a modified version of the GUI for the LTC6803-2 and also
contains a tab to control the LTC3300-1 ICs through the
DC590B USB Serial controller and the second window
reports the status of the LTC3300-1 devices. All the
functions of the LTC6803-2 GUI are supported except
that cell balancing is achieved through the LTC3300-1
ICs by transferring charge from one to six batteries per
LTC3300-1 to the stack or from the stack to one to six
batteries per LTC3300-1.
