Analog Devices LTC6806 | Demoboard DC2192B

Beschreibung

Demonstration circuit 2192B is a fuel cell monitor featuring the LTC6806, a 36-channel fuel cell 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 DC2192B demo circuit also features reversible isoSPI enabling a redundant communication path. The PCB, components and DuraClik connectors are optimized for low EMI susceptibility and emissions. The DC2192B 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 DC2192B isoSPI port (J3/J4 connector). The DC2792B provides two SPI-isoSPI channels for reversible operation.
