DESCRIPTION
Demonstration circuit 2515A is a multicell battery-
stack monitor featuring the
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 demo cir-
cuit also features reversible isoSPI enabling a redundant
communication path.
The DC2515 can communicate to a PC by connecting
directly to a DC2026 Linduino
loaded with the appropriate program (called a "sketch")

Battery-Stack Monitor
to control the battery stack monitor IC and receive data
through a USB serial port. The DC2026C provides a stan-
dard SPI interface which can be connected directly to a
DC2515 board (J4 Connector). Or, the SPI can be trans-
lated 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 SPI-
isoSPI channels for reversible operation.

DEMO MANUAL DC2515A SOFTWARE SETUP The DC2515 can be controlled by the DC2026 Linduino One board. The DC2026 is part of the Arduino compatible Linduino platform that provides example code that will demonstrate how to control the multicell battery stack monitor ICs. - Page 12 DEMO MANUAL DC2515A SOFTWARE SETUP 4. Select the correct COM port to allow communication to DC2026 through USB. Under the Tools menu, select Port → Select the highest number COMxx with the “” check mark symbol. There may be more than one option; DC2026 is usually the highest COM port number.
