Analog Devices Inc. EVAL-ADBMS1818 Demonstration Circuit features the ADBMS1818 18-Cell Battery Monitor. The ADBMS1818 18-Cell Battery Monitors measures up to 18 series-connected battery cells with a total measurement error of less than 3mV. A 2-wire isolated serial interface (isoSPI) can link multiple boards to monitor any number of cells in a stack. The EVAL-ADBMS1818 Demonstration Circuit also provides a reversible isoSPI enabling a fully redundant communication path.
The ADI EVAL-ADBMS1818 Demonstration Circuit communicates 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 EVAL_ADBMS1818.
