Analog Devices LTC6810-1 | Demoboard DC2515B

Description

Demonstration circuit 2515B features the LTC®6810-1, 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.
