DC2100B-D

DC2100B-D is a 12-cell 4A active cell balancer stacked board featuring LTC6804-2 and LTC3300-1(x2). This DC2100B is a bidirectional cell balancer using two LTC®3300-1 ICs to achieve active balancing 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 iso SPI 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.

• GUI uses a USB interface to communicate with the DC2100B-C
• Cell voltage range 3.2V to 4.5V (2.5V to 4.5V) at TA = 25°C
• 60V max stack voltage at TA = 25°C
• 4A (typ) average battery balancing charge current (12 Cells) at TA = 25°C
• 3.4A (typ) average battery balancing charge current (6 cells) at TA = 25°C
• 90% (typ) efficiency at TA = 25°C

Notes

The cell voltage range may be expanded to 2.5V to 4.5V by changing the resistors RTONS to 30.9Kohm and resistors RTONP to 47.5Kohm.
