LTC6804-1

Demonstration Circuit DC2100B-D is a stackable, bidirectional cell balancer slave board using the LTC6804-2 and the LTC3300-1 ICs to achieve active balancing of up to 12 Li-Ion cells. It requires the DC2100B-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 DC2100B-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 DC2100B-D boards can be connected to a DC2100B-C to build a stacked system of eight total boards.

The demonstration circuit DC2792B is an SPI serial to dual-port isoSPI adapter that uses a pair of multiplexed LTC6820 isoSPI transceivers and miniaturized isoSPI connectors (2 contact DuraClik). The board can functionally replace a DC1941 in cases where isoSPI battery-management (BMS) devices are being evaluated, but provides a second isoSPI master to exercise the reversible isoSPI feature where available. The SPI interface can be provided via the legacy 14-contact ribbon cable from either a DC590 or DC2026 USB adapter, or directly installed on the DC2026 as a Linduino shield. The two isoSPI ports are MAIN and AUXiliary, with activity of each indicated by blue LEDs. For use in place of DC1941 or non-reversible isoSPI networks, the MAIN port must be used. Power for the DC2792B comes indirectly from the USB port of the host computer, via the USB to serial adapter being used.
