DC2100A-D - 12 Cell 4A Stackable Slave Bidirectional Active Cell Balancer Featuring LTC6804-2 and LTC3300-1(x2)

Please see the DC2100B for any new designs.

Demonstration Circuit DC2100A-D is a stackable, bidirectional cell balancer slave board using the LTC6804-2 and the LTC®3300-1 ICs to achieve active balancing of up to 12 Li-Ion cells. It requires the DC2100A-C for proper operation. The DC2100B-D uses a single LTC6804-2 Multi-Cell Addressable Battery Stack Monitor IC to measure cell voltages and two LTC3300-1 Synchronous Flyback ICs to provide active cell balancing. The DC2100A-C controller board contains a PIC18F47J53 microcontroller, the LTM2884 isolated USB transceiver, the LTC6804-2, two LTC3300-1 ICs, and the LTC6820 isoSPI Interface IC to facilitate isolated communication. Up to seven DC2100A-D boards can be connected to a DC2100A-C to build a stacked system of eight total boards.
