Evaluation Kits

OBSOLETE: LTC6820 Demo Board | Dual Master isoSPI Adapter

Buy Now View Details

Product Details

This evaluation board is obsolete and no longer recommended.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.

OBSOLETE: LTC6810-1 Demo Board | 6-Channel Battery Stack Monitor with Daisy-chain Interface

Product Details

This evaluation board is obsolete and no longer recommended. The replacement board is the DC2515B.

Demonstration circuit 2515A includes the LTC6810-1, a 6 channel battery-stack monitor. Multiple DC2515A boards can be linked through a 2-wire isolated serial interface (isoSPI) to monitor a long series of cells in a stack.

The DC2515 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 DC2026C provides a standard SPI interface which can be connected directly to a DC2515 board (J4 Connector). Or, the SPI can be translated to isoSPI and then connected to a DC2515 isoSPI port (J2/J1 connector). The DC1941 provides a single SPI-isoSPI channel, and the DC2792 provides two SPIisoSPI channels for reversible operation.

Product Details

Demonstration circuit 2515B features the LTC6810-1, a 6-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 DC2515B 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 DC2515B 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 interface which can be translated to isoSPI and then connected to a DC2515B isoSPI port (J4 or J5 connector). The DC2792B companion board provides two SPI-isoSPI channels for reversible operation.

Product Details

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.
