DC2064A: 10 ~ 55 Vin, up to 12 Li-Ion Cell Balancer

Summary

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 LTC68032 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.
