DEMO MANUAL DC2100B
Bidirectional Cell Balancer
Using the LTC3300-1 and the LTC6804-2
Description
Demonstration Circuit DC2100B is a Bidirectional Cell
Balancer using two
LTC
®
3300-1
ICs to achieve active bal-
ancing of up to 12 Li-Ion cells. The board uses a single
LTC6804-2
Multi-Cell Addressable Battery Stack Monitor
IC to measure cell voltages and two LTC3300-1 ICs to
provide active cell balancing. The DC2100B-C contains
a PIC18F47J53 microcontroller to communicate with the
LTC3300-1 and LTC6804-2 ICs, as well as an LTC6820
isoSPI Interface IC for communication with DC2100B-D
boards. Up to seven DC2100B-D boards can be connected
to a DC2100B-C to build a stacked system of eight total
boards.*
* Note: The voltage rating of T15 limits the system to a total of 8 boards.
A graphical user interface (GUI) uses a USB interface to
communicate with the DC2100B-C. The GUI controls the
LTC3300-1 ICs allowing manual control of the charging/
discharging of cells and reporting the voltage of each cell.
Cell balancing is achieved through the LTC3300-1 ICs by
transferring charge from one or more cells per LTC3300-1
to the stack or from the stack to one or more cells per
LTC3300-1.
