LTC6812-1

This evaluation board is obsolete and no longer recommended. The replacement board is the DC2792B.

Demonstration circuit DC2792A is an SPI serial to dual-port isoSPI adapter that uses a pair of multiplexed LTC6820 isoSPI transceivers. The board can 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, the MAIN port must be used. Power for the DC2792A comes indirectly from the USB port of the host computer, via the USB to serial adapter being used.

This evaluation board is obsolete and no longer recommended. The replacement board is the DC2350A-A.

Demonstration circuit 2350A is a multicell battery stack monitor featuring the LTC6812-1, a 15-cell monitor on the DC2350A-A, or the LTC6813-1, an 18-cell monitor on the DC2350A-B. Multiple boards can be linked through a 2-wire isolated serial interface (isoSPI) to monitor any number of cells in a stack. The demo circuit also features reversible isoSPI enabling a fully redundant communication path.

The DC2350 can communicate to a PC by connecting directly to a DC2026 Linduino^® One. The DC2026 must be loaded with the appropriate program (called a “sketch”) to control the battery stack monitor IC and receive data through a USB serial port. The DC2792/DC1941 can be connected to the DC2026 to provide a fully isolated isoSPI interface to the DC2350.

Demonstration circuit 3036A features the LTC6812-1, a 15-channel battery-stack monitor. Multiple boards can be linked through a 2-wire isolated serial interface (isoSPI^™) to monitor a long series of cells in a stack. The DC3036A demo board also features reversible isoSPI enabling a redundant communication path. The PCB, components, and DuraClik connectors are optimized for Low EMI Susceptibility and Emissions.

The DC3036A can communicate to a PC by connecting a DC2792B dual master isoSPI together with DC2026 Linduino^® One. The DC2026 must be loaded with the appropriate program (called a sketch) to control the battery stack monitor IC and receive data through a USB serial port. The DC2026C provides a standard SPI inter-face which can be translated to isoSPI and then connected to a DC3036A isoSPI port (J4 or J5 connector). The DC2792B companion board provides two SPI-isoSPI channels for reversible operation.

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.
