The EVAL-ADBMS6822 evaluation board is a dual SPI to 2- wire isolated serial-port interface (isoSPI) adapter featuring the ADBMS6822. Multiple ADBMS68xx battery monitors can be linked through daisy-chain interconnections. The EVAL-ADBMS6822 evaluation board also features reversible isoSPI, which enables a redundant communication path to the peripheral units. The PCB, components, and DuraClik™ connectors are optimized for low electromagnetic interference (EMI) susceptibility and emissions.

The EVAL-ADBMS6822 evaluation board can communicate to a PC by connecting together with EVAL-SDP-CK1Z. The EVALADBMS6822 evaluation board provides a standard SPI, which can be translated to isoSPI and then onward to a peripheral device or daisy chain as applicable.

The EVAL-ADBMS6822 evaluation board can also be used to evaluate the ADBMS6821. Note that, for the ADBMS6821, there is only one SPI port; therefore, ignore the second SPI port and auxiliary isoSPI port when using the ADBMS6821.

Full specifications on the ADBMS6822 dual isoSPI adapter are available in the ADBMS6821/ADBMS6822 data sheet available from Analog Devices, Inc., and must be consulted with this user guide when using the EVAL-ADBMS6822 evaluation board.
